67f041be91 docs: add a reference to @lancedb/lance in the docs (#1166)
We aren't yet ready to switch over the examples since almost all JS
examples rely on embeddings and we haven't yet ported those over.
However, this makes it possible for those that are interested to start
using `@lancedb/lancedb`

dfc518b8fb Node SDK Client middleware for HTTP Requests (#1130)
Adds client-side middleware to LanceDB Node SDK to instrument HTTP
Requests

Example - adding `x-request-id` request header:
```js
class HttpMiddleware {
    constructor({ requestId }) {
        this.requestId = requestId
    }

    onRemoteRequest(req, next) {
        req.headers['x-request-id'] = this.requestId
        return next(req)
    }
}

const db = await lancedb.connect({
  uri: 'db://remote-123',
  apiKey: 'sk_...',
})

let tables = await db.withMiddleware(new HttpMiddleware({ requestId: '123' })).tableNames();

```

7d790bd9e7 feat: introduce ArrowNative wrapper struct for adding data that is already a RecordBatchReader (#1139)
In
2de226220b
I added a new `IntoArrow` trait for adding data into a table.
Unfortunately, it seems my approach for implementing the trait for
"things that are already record batch readers" was flawed. This PR
corrects that flaw and, conveniently, removes the need to box readers at
all (though it is ok if you do).

dbdd0a7b4b Order by field support FTS (#1132)
This PR adds support for passing through a set of ordering fields at
index time (unsigned ints that tantivity can use as fast_fields) that at
query time you can sort your results on. This is useful for cases where
you want to get related hits, i.e by keyword, but order those hits by
some other score, such as popularity.

I.e search for songs descriptions that match on "sad AND jazz AND 1920"
and then order those by number of times played. Example usage can be
seen in the fts tests.

51bdbcad98 feat: change DistanceType to be independent thing instead of resuing lance_linalg (#1133)
This PR originated from a request to add `Serialize` / `Deserialize` to
`lance_linalg::distance::DistanceType`. However, that is a strange
request for `lance_linalg` which shouldn't really have to worry about
`Serialize` / `Deserialize`. The problem is that `lancedb` is re-using
`DistanceType` and things in `lancedb` do need to worry about
`Serialize`/`Deserialize` (because `lancedb` needs to support remote
client).

On the bright side, separating the two types allows us to independently
document distance type and allows `lance_linalg` to make changes to
`DistanceType` in the future without having to worry about backwards
compatibility concerns.

d974413745 fix(python): Add python azure blob read support (#1102)
I know there's a larger effort to have the python client based on the
core rust implementation, but in the meantime there have been several
issues (#1072 and #485) with some of the azure blob storage calls due to
pyarrow not natively supporting an azure backend. To this end, I've
added an optional import of the fsspec implementation of azure blob
storage [`adlfs`](https://pypi.org/project/adlfs/) and passed it to
`pyarrow.fs`. I've modified the existing test and manually verified it
with some real credentials to make sure it behaves as expected.

It should be now as simple as:

```python
import lancedb

db = lancedb.connect("az://blob_name/path")
table = db.open_table("test")
table.search(...)
```

Thank you for this cool project and we're excited to start using this
for real shortly! 🎉 And thanks to @dwhitena for bringing it to my
attention with his prediction guard posts.

dbec598610 feat(python): support optional vector field in pydantic model (#1097)
The LanceDB embeddings registry allows users to annotate the pydantic
model used as table schema with the desired embedding function, e.g.:

```python
class Schema(LanceModel):
    id: str
    vector: Vector(openai.ndims()) = openai.VectorField()
    text: str = openai.SourceField()
```

Tables created like this does not require embeddings to be calculated by
the user explicitly, e.g. this works:

```python
table.add([{"id": "foo", "text": "rust all the things"}])
```

However, trying to construct pydantic model instances without vector
doesn't because it's a required field.

Instead, you need add a default value:

```python
class Schema(LanceModel):
    id: str
    vector: Vector(openai.ndims()) = openai.VectorField(default=None)
    text: str = openai.SourceField()
```

then this completes without errors:
```python
table.add([Schema(id="foo", text="rust all the things")])
```

However, all of the vectors are filled with zeros. Instead in
add_vector_col we have to add an additional check so that the embedding
generation is called.

9148cd6d47 feat: page_token / limit to native table_names function. Use async table_names function from sync table_names function (#1059)
The synchronous table_names function in python lancedb relies on arrow's
filesystem which behaves slightly differently than object_store. As a
result, the function would not work properly in GCS.

However, the async table_names function uses object_store directly and
thus is accurate. In most cases we can fallback to using the async
table_names function and so this PR does so. The one case we cannot is
if the user is already in an async context (we can't start a new async
event loop). Soon, we can just redirect those users to use the async API
instead of the sync API and so that case will eventually go away. For
now, we fallback to the old behavior.

d6f0663671 fix(python): Few fts patches (#1039)
1. filtering with fts mutated the schema, which caused schema mistmatch
problems with hybrid search as it combines fts and vector search tables.
2. fts with filter failed with `with_row_id`. This was because row_id
was calculated before filtering which caused size mismatch on attaching
it after.
3. The fix for 1 meant that now row_id is attached before filtering but
passing a filter to `to_lance` on a dataset that already contains
`_rowid` raises a panic from lance. So temporarily, in case where fts is
used with a filter AND `with_row_id`, we just force user to using the
duckdb pathway.

ea33b68c6c fix: sanitize foreign schemas (#1058)
Arrow-js uses brittle `instanceof` checks throughout the code base.
These fail unless the library instance that produced the object matches
exactly the same instance the vectordb is using. At a minimum, this
means that a user using arrow version 15 (or any version that doesn't
match exactly the version that vectordb is using) will get strange
errors when they try and use vectordb.

However, there are even cases where the versions can be perfectly
identical, and the instanceof check still fails. One such example is
when using `vite` (e.g. https://github.com/vitejs/vite/issues/3910)

This PR solves the problem in a rather brute force, but workable,
fashion. If we encounter a schema that does not pass the `instanceof`
check then we will attempt to sanitize that schema by traversing the
object and, if it has all the correct properties, constructing an
appropriate `Schema` instance via deep cloning.

1453bf4e7a feat: reconfigure typescript linter / formatter for nodejs (#1042)
The eslint rules specify some formatting requirements that are rather
strict and conflict with vscode's default formatter. I was unable to get
auto-formatting to setup correctly. Also, eslint has quite recently
[given up on
formatting](https://eslint.org/blog/2023/10/deprecating-formatting-rules/)
and recommends using a 3rd party formatter.

This PR adds prettier as the formatter. It restores the eslint rules to
their defaults. This does mean we now have the "no explicit any" check
back on. I know that rule is pedantic but it did help me catch a few
corner cases in type testing that weren't covered in the current code.
Leaving in draft as this is dependent on other PRs.

abaf315baf feat: add support for add to async python API (#1037)
In order to add support for `add` we needed to migrate the rust `Table`
trait to a `Table` struct and `TableInternal` trait (similar to the way
the connection is designed).

While doing this we also cleaned up some inconsistencies between the
SDKs:

* Python and Node are garbage collected languages and it can be
difficult to trigger something to be freed. The convention for these
languages is to have some kind of close method. I added a close method
to both the table and connection which will drop the underlying rust
object.
* We made significant improvements to table creation in
cc5f2136a6
for the `node` SDK. I copied these changes to the `nodejs` SDK.
* The nodejs tables were using fs to create tmp directories and these
were not getting cleaned up. This is mostly harmless but annoying and so
I changed it up a bit to ensure we cleanup tmp directories.
* ~~countRows in the node SDK was returning `bigint`. I changed it to
return `number`~~ (this actually happened in a previous PR)
* Tables and connections now implement `std::fmt::Display` which is
hooked into python's `__repr__`. Node has no concept of a regular "to
string" function and so I added a `display` method.
* Python method signatures are changing so that optional parameters are
always `Optional[foo] = None` instead of something like `foo = False`.
This is because we want those defaults to be in rust whenever possible
(though we still need to mention the default in documentation).
* I changed the python `AsyncConnection/AsyncTable` classes from
abstract classes with a single implementation to just classes because we
no longer have the remote implementation in python.

Note: this does NOT add the `add` function to the remote table. This PR
was already large enough, and the remote implementation is unique
enough, that I am going to do all the remote stuff at a later date (we
should have the structure in place and correct so there shouldn't be any
refactor concerns)

a6bcbd007b feat: add a basic async python client starting point (#1014)
This changes `lancedb` from a "pure python" setuptools project to a
maturin project and adds a rust lancedb dependency.

The async python client is extremely minimal (only `connect` and
`Connection.table_names` are supported). The purpose of this PR is to
get the infrastructure in place for building out the rest of the async
client.

Although this is not technically a breaking change (no APIs are
changing) it is still a considerable change in the way the wheels are
built because they now include the native shared library.

f1596122e6 refactor: rename the rust crate from vectordb to lancedb (#1012)
This also renames the new experimental node package to lancedb. The
classic node package remains named vectordb.

The goal here is to avoid introducing piecemeal breaking changes to the
vectordb crate. Instead, once the new API is stabilized, we will
officially release the lancedb crate and deprecate the vectordb crate.
The same pattern will eventually happen with the npm package vectordb.

f04590ddad refactor: rust vectordb API stabilization of the Connection trait (#993)
This is the start of a more comprehensive refactor and stabilization of
the Rust API. The `Connection` trait is cleaned up to not require
`lance` and to match the `Connection` trait in other APIs. In addition,
the concrete implementation `Database` is hidden.

BREAKING CHANGE: The struct `crate::connection::Database` is now gone.
Several examples opened a connection using `Database::connect` or
`Database::connect_with_params`. Users should now use
`vectordb::connect`.

BREAKING CHANGE: The `connect`, `create_table`, and `open_table` methods
now all return a builder object. This means that a call like
`conn.open_table(..., opt1, opt2)` will now become
`conn.open_table(...).opt1(opt1).opt2(opt2).execute()` In addition, the
structure of options has changed slightly. However, no options
capability has been removed.

57605a2d86 feat(python): add read_consistency_interval argument (#828)
This PR refactors how we handle read consistency: does the `LanceTable`
class always pick up modifications to the table made by other instance
or processes. Users have three options they can set at the connection
level:

1. (Default) `read_consistency_interval=None` means it will not check at
all. Users can call `table.checkout_latest()` to manually check for
updates.
2. `read_consistency_interval=timedelta(0)` means **always** check for
updates, giving strong read consistency.
3. `read_consistency_interval=timedelta(seconds=20)` means check for
updates every 20 seconds. This is eventual consistency, a compromise
between the two options above.

## Table reference state

There is now an explicit difference between a `LanceTable` that tracks
the current version and one that is fixed at a historical version. We
now enforce that users cannot write if they have checked out an old
version. They are instructed to call `checkout_latest()` before calling
the write methods.

Since `conn.open_table()` doesn't have a parameter for version, users
will only get fixed references if they call `table.checkout()`.

The difference between these two can be seen in the repr: Table that are
fixed at a particular version will have a `version` displayed in the
repr. Otherwise, the version will not be shown.

```python
>>> table
LanceTable(connection=..., name="my_table")
>>> table.checkout(1)
>>> table
LanceTable(connection=..., name="my_table", version=1)
```

I decided to not create different classes for these states, because I
think we already have enough complexity with the Cloud vs OSS table
references.

a248d7feec fix: add request retry to python client (#917)
Adds capability to the remote python SDK to retry requests (fixes #911)

This can be configured through environment:
- `LANCE_CLIENT_MAX_RETRIES`= total number of retries. Set to 0 to
disable retries. default = 3
- `LANCE_CLIENT_CONNECT_RETRIES` = number of times to retry request in
case of TCP connect failure. default = 3
- `LANCE_CLIENT_READ_RETRIES` = number of times to retry request in case
of HTTP request failure. default = 3
- `LANCE_CLIENT_RETRY_STATUSES` = http statuses for which the request
will be retried. passed as comma separated list of ints. default `500,
502, 503`
- `LANCE_CLIENT_RETRY_BACKOFF_FACTOR` = controls time between retry
requests. see
[here](23f2287eb5/src/urllib3/util/retry.py (L141-L146)).
default = 0.25

Only read requests will be retried:
- list table names
- query
- describe table
- list table indices

This does not add retry capabilities for writes as it could possibly
cause issues in the case where the retried write isn't idempotent. For
example, in the case where the LB times-out the request but the server
completes the request anyway, we might not want to blindly retry an
insert request.

3ffed89793 feat(python): Hybrid search & Reranker API (#824)
based on https://github.com/lancedb/lancedb/pull/713
- The Reranker api can be plugged into vector only or fts only search
but this PR doesn't do that (see example -
https://txt.cohere.com/rerank/)


### Default reranker -- `LinearCombinationReranker(weight=0.7,
fill=1.0)`

```
table.search("hello", query_type="hybrid").rerank(normalize="score").to_pandas()
```
### Available rerankers
LinearCombinationReranker
```
from lancedb.rerankers import LinearCombinationReranker

# Same as default 
table.search("hello", query_type="hybrid").rerank(
                                      normalize="score", 
                                      reranker=LinearCombinationReranker()
                                     ).to_pandas()

# with custom params
reranker = LinearCombinationReranker(weight=0.3, fill=1.0)
table.search("hello", query_type="hybrid").rerank(
                                      normalize="score", 
                                      reranker=reranker
                                     ).to_pandas()
```

Cohere Reranker
```
from lancedb.rerankers import CohereReranker

# default model.. English and multi-lingual supported. See docstring for available custom params
table.search("hello", query_type="hybrid").rerank(
                                      normalize="rank",  # score or rank
                                      reranker=CohereReranker()
                                     ).to_pandas()

```

CrossEncoderReranker

```
from lancedb.rerankers import CrossEncoderReranker

table.search("hello", query_type="hybrid").rerank(
                                      normalize="rank", 
                                      reranker=CrossEncoderReranker()
                                     ).to_pandas()

```

## Using custom Reranker
```
from lancedb.reranker import Reranker

class CustomReranker(Reranker):
    def rerank_hybrid(self, vector_result, fts_result):
           combined_res = self.merge_results(vector_results, fts_results) # or use custom combination logic
           # Custom rerank logic here
           
           return combined_res
```

- [x] Expand testing
- [x] Make sure usage makes sense
- [x] Run simple benchmarks for correctness (Seeing weird result from
cohere reranker in the toy example)
- Support diverse rerankers by default:
- [x] Cross encoding
- [x] Cohere
- [x] Reciprocal Rank Fusion

8f54cfcde9 Docs updates incl. Polars (#827)
This PR makes the following aesthetic and content updates to the docs.

- [x] Fix max width issue on mobile: Content should now render more
cleanly and be more readable on smaller devices
- [x] Improve image quality of flowchart in data management page
- [x] Fix syntax highlighting in text at the bottom of the IVF-PQ
concepts page
- [x] Add example of Polars LazyFrames to docs (Integrations)
- [x] Add example of adding data to tables using Polars (guides)

119b928a52 docs: Updates and refactor (#683)
This PR makes incremental changes to the documentation.

* Closes #697 
* Closes #698

## Chores
- [x] Add dark mode
- [x] Fix headers in navbar
- [x] Add `extra.css` to customize navbar styles
- [x] Customize fonts for prose/code blocks, navbar and admonitions
- [x] Inspect all admonition boxes (remove redundant dropdowns) and
improve clarity and readability
- [x] Ensure that all images in the docs have white background (not
transparent) to be viewable in dark mode
- [x] Improve code formatting in code blocks to make them consistent
with autoformatters (eslint/ruff)
- [x] Add bolder weight to h1 headers
- [x] Add diagram showing the difference between embedded (OSS) and
serverless (Cloud)
- [x] Fix [Creating an empty
table](https://lancedb.github.io/lancedb/guides/tables/#creating-empty-table)
section: right now, the subheaders are not clickable.
- [x] In critical data ingestion methods like `table.add` (among
others), the type signature often does not match the actual code
- [x] Proof-read each documentation section and rewrite as necessary to
provide more context, use cases, and explanations so it reads less like
reference documentation. This is especially important for CRUD and
search sections since those are so central to the user experience.

## Restructure/new content 
- [x] The section for [Adding
data](https://lancedb.github.io/lancedb/guides/tables/#adding-to-a-table)
only shows examples for pandas and iterables. We should include pydantic
models, arrow tables, etc.
- [x] Add conceptual tutorial for IVF-PQ index
- [x] Clearly separate vector search, FTS and filtering sections so that
these are easier to find
- [x] Add docs on refine factor to explain its importance for recall.
Closes #716
- [x] Add an FAQ page showing answers to commonly asked questions about
LanceDB. Closes #746
- [x] Add simple polars example to the integrations section. Closes #756
and closes #153
- [ ] Add basic docs for the Rust API (more detailed API docs can come
later). Closes #781
- [x] Add a section on the various storage options on local vs. cloud
(S3, EBS, EFS, local disk, etc.) and the tradeoffs involved. Closes #782
- [x] Revamp filtering docs: add pre-filtering examples and redo headers
and update content for SQL filters. Closes #783 and closes #784.
- [x] Add docs for data management: compaction, cleaning up old versions
and incremental indexing. Closes #785
- [ ] Add a benchmark section that also discusses some best practices.
Closes #787

By default it is set to False, so trying to create
a table with the same name will raise an exception.
If set to True, then it only opens the table if it
already exists. If you pass in a schema, it will
be checked against the existing table to make sure
you get what you want. If you pass in data, it will
NOT be added to the existing table.

dc8d6835c0 feat: add timezone handling for datetime in pydantic (#578)
If you add timezone information in the Field annotation for a datetime
then that will now be passed to the pyarrow data type.

I'm not sure how pyarrow enforces timezones, right now, it silently
coerces to the timezone given in the column regardless of whether the
input had the matching timezone or not. This is probably not the right
behavior. Though we could just make it so the user has to make the
pydantic model do the validation instead of doing that at the pyarrow
conversion layer.

f55d99cec5 feat(python): add post filtering for full text search (#739)
Closes #721 

fts will return results as a pyarrow table. Pyarrow tables has a
`filter` method but it does not take sql filter strings (only pyarrow
compute expressions). Instead, we do one of two things to support
`tbl.search("keywords").where("foo=5").limit(10).to_arrow()`:

Default path: If duckdb is available then use duckdb to execute the sql
filter string on the pyarrow table.
Backup path: Otherwise, write the pyarrow table to a lance dataset and
then do `to_table(filter=<filter>)`

Neither is ideal. 
Default path has two issues:
1. requires installing an extra library (duckdb)
2. duckdb mangles some fields (like fixed size list => list)

Backup path incurs a latency penalty (~20ms on ssd) to write the
resultset to disk.

In the short term, once #676 is addressed, we can write the dataset to
"memory://" instead of disk, this makes the post filter evaluate much
quicker (ETA next week).

In the longer term, we'd like to be able to evaluate the filter string
on the pyarrow Table directly, one possibility being that we use
Substrait to generate pyarrow compute expressions from sql string. Or if
there's enough progress on pyarrow, it could support Substrait
expressions directly (no ETA)

upstream so None's are not added to the document.
If all of the indexed fields are None then we skip

7d55a94efd Add relevant imports for each step (#764)
I found that it was quite incoherent to have to read through the
documentation and having to search which submodule that each class
should be imported from.

For example, it is cumbersome to have to navigate to another
documentation page to find out that `EmbeddingFunctionRegistry` is from
`lancedb.embeddings`

4b8af261a3 feat: add timezone handling for datetime in pydantic (#578)
If you add timezone information in the Field annotation for a datetime
then that will now be passed to the pyarrow data type.

I'm not sure how pyarrow enforces timezones, right now, it silently
coerces to the timezone given in the column regardless of whether the
input had the matching timezone or not. This is probably not the right
behavior. Though we could just make it so the user has to make the
pydantic model do the validation instead of doing that at the pyarrow
conversion layer.

c8728d4ca1 feat(python): add post filtering for full text search (#739)
Closes #721 

fts will return results as a pyarrow table. Pyarrow tables has a
`filter` method but it does not take sql filter strings (only pyarrow
compute expressions). Instead, we do one of two things to support
`tbl.search("keywords").where("foo=5").limit(10).to_arrow()`:

Default path: If duckdb is available then use duckdb to execute the sql
filter string on the pyarrow table.
Backup path: Otherwise, write the pyarrow table to a lance dataset and
then do `to_table(filter=<filter>)`

Neither is ideal. 
Default path has two issues:
1. requires installing an extra library (duckdb)
2. duckdb mangles some fields (like fixed size list => list)

Backup path incurs a latency penalty (~20ms on ssd) to write the
resultset to disk.

In the short term, once #676 is addressed, we can write the dataset to
"memory://" instead of disk, this makes the post filter evaluate much
quicker (ETA next week).

In the longer term, we'd like to be able to evaluate the filter string
on the pyarrow Table directly, one possibility being that we use
Substrait to generate pyarrow compute expressions from sql string. Or if
there's enough progress on pyarrow, it could support Substrait
expressions directly (no ETA)

For object detection, each row may correspond to an image and each image

`bbox` field is potentially "list of list of float". This adds support
in our pydantic-pyarrow conversion for nested lists.

f9dd7a5d8a fix: prevent duplicate data in FTS index (#728)
This forces the user to replace the whole FTS directory when re-creating
the index, prevent duplicate data from being created. Previously, the
whole dataset was re-added to the existing index, duplicating existing
rows in the index.

This (in combination with lancedb/lance#1707) caused #726, since the
duplicate data emitted duplicate indices for `take()` and an upstream
issue caused those queries to fail.

This solution isn't ideal, since it makes the FTS index temporarily
unavailable while the index is built. In the future, we should have
multiple FTS index directories, which would allow atomic commits of new
indexes (as well as multiple indexes for different columns).

Fixes #498.
Fixes #726.

Closes https://github.com/lancedb/lance/issues/1738

We add a `flatten` parameter to the signature of `to_pandas`. By default
this is None and does nothing.
If set to True or -1, then LanceDB will flatten structs before
converting to a pandas dataframe. All nested structs are also flattened.
If set to any positive integer, then LanceDB will flatten structs up to
the specified level of nesting.

Added the prefilter flag argument to the `LanceQueryBuilder.where`.

This should make it display here:

https://lancedb.github.io/lancedb/python/python/#lancedb.query.LanceQueryBuilder.select

And also in intellisense like this:

Also adds some improved documentation about the `where` argument to this
method.

cd9debc3b7 fix(python): fix multiple embedding functions bug (#597)
Closes #594

The embedding functions are pydantic models so multiple instances with
the same parameters are considered ==, which means that if you have
multiple embedding columns it's possible for the embeddings to get
overwritten. Instead we use `is` instead of == to avoid this problem.

testing: modified unit test to include this case

26a97ba997 feat: add checkout method to table to reuse existing store and connections (#593)
Prior to this PR, to get a new version of a table, we need to re-open
the table. This has a few downsides w.r.t. performance:
* Object store is recreated, which takes time and throws away existing
warm connections
* Commit handler is thrown aways as well, which also may contain warm
connections

# This workflow increments versions, tags the version, and pushes it.
# When a tag is pushed, another workflow is triggered that creates a GH release
# and uploads the binaries. This workflow is only for creating the tag.
# This script will enforce that a minor version is incremented if there are any
# breaking changes since the last minor increment. However, it isn't able to
# differentiate between breaking changes in Node versus Python. If you wish to
# bypass this check, you can manually increment the version and push the tag.

Stable releases are created about every 2 weeks. For the latest features and bug
fixes, you can install the preview release. These releases receive the same
level of testing as stable releases, but are not guaranteed to be available for
more than 6 months after they are released. Once your application is stable, we
recommend switching to stable releases.

slowly deprecating `vectordb` in favor of `lancedb`. There is a

## Using the Embedding API
You can use the embedding API when working with embedding models. It automatically vectorizes the data at ingestion and query time and comes with built-in integrations with popular embedding models like Openai, Hugging Face, Sentence Transformers, CLIP and more.
If you're using the `vectordb` module in JavaScript, since LanceDB contains a prebuilt Node binary, you must configure `next.config.js` to exclude it from webpack. This is required for both using Next.js and deploying a LanceDB app on Vercel.

config.externals.push({ vectordb: 'vectordb' })
return config;
}

Learn about using the existing integrations and creating custom embedding functions in the [embedding API guide](./embeddings/).
## What's next
This section covered the very basics of using LanceDB. If you're learning about vector databases for the first time, you may want to read the page on [indexing](concepts/index_ivfpq.md) to get familiar with the concepts.
If you've already worked with other vector databases, you may want to read the [guides](guides/tables.md) to learn how to work with LanceDB in more detail.
[^1]: The `vectordb` package is a legacy package that is deprecated in favor of `@lancedb/lancedb`. The `vectordb` package will continue to receive bug fixes and security updates until September 2024. We recommend all new projects use `@lancedb/lancedb`. See the [migration guide](migration.md) for more information.

# CLI & Config
## LanceDB CLI
Once lanceDB is installed, you can access the CLI using `lancedb` command on the console.
```
lancedb
```
This lists out all the various command-line options available. You can get the usage or help for a particular command.
```
lancedb {command} --help
```
## LanceDB config
LanceDB uses a global config file to store certain settings. These settings are configurable using the lanceDB cli.
To view your config settings, you can use:
```
lancedb config
```
These config parameters can be tuned using the cli.
```
lancedb {config_name} --{argument}
```
## LanceDB Opt-in Diagnostics
When enabled, LanceDB will send anonymous events to help us improve LanceDB. These diagnostics are used only for error reporting and no data is collected. Error & stats allow us to automate certain aspects of bug reporting, prioritization of fixes and feature requests.
These diagnostics are opt-in and can be enabled or disabled using the `lancedb diagnostics` command. These are enabled by default.
### Get usage help
```
lancedb diagnostics --help
```
### Disable diagnostics
```
lancedb diagnostics --disabled
```
### Enable diagnostics

### Cohere Embeddings
Using cohere API requires cohere package, which can be installed using `pip install cohere`. Cohere embeddings are used to generate embeddings for text data. The embeddings can be used for various tasks like semantic search, clustering, and classification.
You also need to set the `COHERE_API_KEY` environment variable to use the Cohere API.
Supported models are:
```
* embed-english-v3.0
* embed-multilingual-v3.0
* embed-english-light-v3.0
* embed-multilingual-light-v3.0
* embed-english-v2.0
* embed-english-light-v2.0
* embed-multilingual-v2.0
```
Supported parameters (to be passed in `create` method) are:
| Parameter | Type | Default Value | Description |
|---|---|---|---|
| `name` | `str` | `"embed-english-v2.0"` | The model ID of the cohere model to use. Supported base models for Text Embeddings: embed-english-v3.0, embed-multilingual-v3.0, embed-english-light-v3.0, embed-multilingual-light-v3.0, embed-english-v2.0, embed-english-light-v2.0, embed-multilingual-v2.0 |
| `source_input_type` | `str` | `"search_document"` | The type of input data to be used for the source column. |
| `query_input_type` | `str` | `"search_query"` | The type of input data to be used for the query. |
Cohere supports following input types:
| Input Type | Description |
|-------------------------|---------------------------------------|
| "`search_document`" | Used for embeddings stored in a vector|
| | database for search use-cases. |
| "`search_query`" | Used for embeddings of search queries |
| | run against a vector DB |
| "`semantic_similarity`" | Specifies the given text will be used |
| | for Semantic Textual Similarity (STS) |
| "`classification`" | Used for embeddings passed through a |
| | text classifier. |
| "`clustering`" | Used for the embeddings run through a |
| | clustering algorithm |
Usage Example:
```python
import lancedb
from lancedb.pydantic import LanceModel, Vector
from lancedb.embeddings import EmbeddingFunctionRegistry
cohere = EmbeddingFunctionRegistry
.get_instance()
.get("cohere")

{ "text": "goodbye world" }]
db = lancedb.connect("~/.lancedb")
tbl = db.create_table("test", schema=TextModel, mode="overwrite")
tbl.add(data)
```
### Jina Embeddings
Jina embeddings are used to generate embeddings for text and image data.
You also need to set the `JINA_API_KEY` environment variable to use the Jina API.
You can find a list of supported models under [https://jina.ai/embeddings/](https://jina.ai/embeddings/)

# IBM watsonx.ai Embeddings
Generate text embeddings using IBM's watsonx.ai platform.
## Supported Models
You can find a list of supported models at [IBM watsonx.ai Documentation](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-models-embed.html?context=wx). The currently supported model names are:
- `ibm/slate-125m-english-rtrvr`
- `ibm/slate-30m-english-rtrvr`
- `sentence-transformers/all-minilm-l12-v2`
- `intfloat/multilingual-e5-large`
## Parameters
The following parameters can be passed to the `create` method:
| Parameter | Type | Default Value | Description |
|------------|----------|----------------------------------|-----------------------------------------------------------|
| name | str | "ibm/slate-125m-english-rtrvr" | The model ID of the watsonx.ai model to use |
| api_key | str | None | Optional IBM Cloud API key (or set `WATSONX_API_KEY`) |

Due to the nature of vector embeddings, they can be used to represent any kind of data, from text to images to audio.
This makes them a very powerful tool for machine learning practitioners.
However, there's no one-size-fits-all solution for generating embeddings - there are many different libraries and APIs
(both commercial and open source) that can be used to generate embeddings from structured/unstructured data.
LanceDB supports 3 methods of working with embeddings.
1. You can manually generate embeddings for the data and queries. This is done outside of LanceDB.
2. You can use the built-in [embedding functions](./embedding_functions.md) to embed the data and queries in the background.
3. You can define your own [custom embedding function](./custom_embedding_function.md)
3. For python users, you can define your own [custom embedding function](./custom_embedding_function.md)
that extends the default embedding functions.
For python users, there is also a legacy [with_embeddings API](./legacy.md).
It is retained for compatibility and will be removed in a future version.
## Quickstart
To get started with embeddings, you can use the built-in embedding functions.
### OpenAI Embedding function
LanceDB registers the OpenAI embeddings function in the registry as `openai`. You can pass any supported model name to the `create`. By default it uses `"text-embedding-ada-002"`.
=== "Python"
```python
import lancedb
from lancedb.pydantic import LanceModel, Vector

db = lancedb.connect("/tmp/db")

table = db.create_table("words", schema=Words, mode="overwrite")
table.add(
[
{"text": "hello world"},
{"text": "goodbye world"}
]

query = "greetings"
actual = table.search(query).limit(1).to_pydantic(Words)[0]
print(actual.text)

```
=== "Rust"
```rust
--8<--- "rust/lancedb/examples/openai.rs:imports"
--8<--- "rust/lancedb/examples/openai.rs:openai_embeddings"
```
### Sentence Transformers Embedding function
LanceDB registers the Sentence Transformers embeddings function in the registry as `sentence-transformers`. You can pass any supported model name to the `create`. By default it uses `"sentence-transformers/paraphrase-MiniLM-L6-v2"`.
=== "Python"
```python
import lancedb
from lancedb.pydantic import LanceModel, Vector
from lancedb.embeddings import get_registry
db = lancedb.connect("/tmp/db")

query = "greetings"
actual = table.search(query).limit(1).to_pydantic(Words)[0]
print(actual.text)
```

### Embedding function with LanceDB cloud
Embedding functions are now supported on LanceDB cloud. The embeddings will be generated on the source device and sent to the cloud. This means that the source device must have the necessary resources to generate the embeddings. Here's an example using the OpenAI embedding function:
```python
import os
import lancedb
from lancedb.pydantic import LanceModel, Vector
from lancedb.embeddings import get_registry
os.environ['OPENAI_API_KEY'] = "..."
db = lancedb.connect(
uri="db://....",
api_key="sk_...",
region="us-east-1"
)
func = get_registry().get("openai").create()
class Words(LanceModel):
text: str = func.SourceField()
vector: Vector(func.ndims()) = func.VectorField()
table = db.create_table("words", schema=Words)
table.add(
[
{"text": "hello world"},
{"text": "goodbye world"}
]
)
query = "greetings"
actual = table.search(query).limit(1).to_pydantic(Words)[0]
print(actual.text)
```
It is retained for compatibility and will be removed in a future version.

# Full-text search
LanceDB provides support for full-text search via Lance (before via [Tantivy](https://github.com/quickwit-oss/tantivy) (Python only)), allowing you to incorporate keyword-based search (based on BM25) in your retrieval solutions.
LanceDB provides support for full-text search via [Tantivy](https://github.com/quickwit-oss/tantivy) (currently Python only), allowing you to incorporate keyword-based search (based on BM25) in your retrieval solutions. Our goal is to push the FTS integration down to the Rust level in the future, so that it's available for Rust and JavaScript users as well. Follow along at [this Github issue](https://github.com/lancedb/lance/issues/1195)
Currently, the Lance full text search is missing some features that are in the Tantivy full text search. This includes phrase queries, re-ranking, and customizing the tokenizer. Thus, in Python, Tantivy is still the default way to do full text search and many of the instructions below apply just to Tantivy-based indices.
A hybrid search solution combining vector and full-text search is also on the way.
## Installation (Only for Tantivy-based FTS)
!!! note
No need to install the tantivy dependency if using native FTS

```
```typescript
import * as lancedb from "@lancedb/lancedb";
const uri = "data/sample-lancedb"
const db = await lancedb.connect(uri);
To search an FTS index via keywords, LanceDB's `table.search` accepts a string as input:
const data = [
{ vector: [3.1, 4.1], text: "Frodo was a happy puppy" },
{ vector: [5.9, 26.5], text: "There are several kittens playing" },
];
const tbl = await db.createTable("my_table", data, { mode: "overwrite" });
await tbl.createIndex("text", {

});
```python
table.search("puppy").limit(10).select(["text"]).to_list()
```
await tbl
.search("puppy")
.select(["text"])
.limit(10)

This returns the result as a list of dictionaries as follows.

```
It would search on all indexed columns by default, so it's useful when there are multiple indexed columns.
For now, this is supported in tantivy way only.
Passing `fts_columns="text"` if you want to specify the columns to search, but it's not available for Tantivy-based full text search.
```python
[{'text': 'Frodo was a happy puppy', 'score': 0.6931471824645996}]
```
!!! note
LanceDB automatically searches on the existing FTS index if the input to the search is of type `str`. If you provide a vector as input, LanceDB will search the ANN index instead.
## Tokenization
By default the text is tokenized by splitting on punctuation and whitespaces and then removing tokens that are longer than 40 chars. For more language specific tokenization then provide the argument tokenizer_name with the 2 letter language code followed by "_stem". So for english it would be "en_stem".
For now, only the Tantivy-based FTS index supports to specify the tokenizer, so it's only available in Python with `use_tantivy=True`.

```python
table.create_fts_index("text", use_tantivy=True, tokenizer_name="en_stem")

# Building Scalar Index
Similar to many SQL databases, LanceDB supports several types of Scalar indices to accelerate search
over scalar columns.
- `BTREE`: The most common type is BTREE. This index is inspired by the btree data structure
although only the first few layers of the btree are cached in memory.
It will perform well on columns with a large number of unique values and few rows per value.
- `BITMAP`: this index stores a bitmap for each unique value in the column.
This index is useful for columns with a finite number of unique values and many rows per value.
For example, columns that represent "categories", "labels", or "tags"
- `LABEL_LIST`: a special index that is used to index list columns whose values have a finite set of possibilities.
For example, a column that contains lists of tags (e.g. `["tag1", "tag2", "tag3"]`) can be indexed with a `LABEL_LIST` index.
| Data Type | Filter | Index Type |
| --------------------------------------------------------------- | ----------------------------------------- | ------------ |
| Numeric, String, Temporal | `<`, `=`, `>`, `in`, `between`, `is null` | `BTREE` |
| Boolean, numbers or strings with fewer than 1,000 unique values | `<`, `=`, `>`, `in`, `between`, `is null` | `BITMAP` |
| List of low cardinality of numbers or strings | `array_has_any`, `array_has_all` | `LABEL_LIST` |

{"book_id": 2, "publisher": "book town", "tags": ["non-fiction"]},
{"book_id": 3, "publisher": "oreilly", "tags": ["textbook"]}
]

const tbl = await db.openTable("my_vectors");
await tbl.create_index("book_id");
await tlb.create_index("publisher", { config: lancedb.Index.bitmap() })
```
For example, the following scan will be faster if the column `my_col` has a scalar index:
=== "Python"
```python
import lancedb
table = db.open_table("books")
my_df = table.search().where("book_id = 2").to_pandas()

LanceDB OSS uses the [object-store](https://docs.rs/object_store/latest/object_store/) Rust crate for object store access. There are general environment variables that can be used to configure the object store, such as the request timeout and proxy configuration. See the [object_store ClientConfigKey](https://docs.rs/object_store/latest/object_store/enum.ClientConfigKey.html) doc for available configuration options. The environment variables that can be set are the snake-cased versions of these variable names. For example, to set `ProxyUrl` use the environment variable `PROXY_URL`.

!!! info "Storage option casing"
The storage option keys are case-insensitive. So `connect_timeout` and `CONNECT_TIMEOUT` are the same setting. Usually lowercase is used in the `storage_options` argument and uppercase is used for environment variables. In the `lancedb` Node package, the keys can also be provided in `camelCase` capitalization. For example, `connectTimeout` is equivalent to `connect_timeout`.
### General configuration
There are several options that can be set for all object stores, mostly related to network client configuration.
<!-- from here: https://docs.rs/object_store/latest/object_store/enum.ClientConfigKey.html -->
| Key | Description |
|----------------------------|--------------------------------------------------------------------------------------------------|
| `allow_http` | Allow non-TLS, i.e. non-HTTPS connections. Default: `False`. |
| `allow_invalid_certificates`| Skip certificate validation on HTTPS connections. Default: `False`. |
| `connect_timeout` | Timeout for only the connect phase of a Client. Default: `5s`. |
| `timeout` | Timeout for the entire request, from connection until the response body has finished. Default: `30s`. |
| `user_agent` | User agent string to use in requests. |
| `proxy_url` | URL of a proxy server to use for requests. Default: `None`. |
| `proxy_ca_certificate` | PEM-formatted CA certificate for proxy connections. |
| `proxy_excludes` | List of hosts that bypass the proxy. This is a comma-separated list of domains and IP masks. Any subdomain of the provided domain will be bypassed. For example, `example.com, 192.168.1.0/24` would bypass `https://api.example.com`, `https://www.example.com`, and any IP in the range `192.168.1.0/24`. |
### AWS S3
To configure credentials for AWS S3, you can use the `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and `AWS_SESSION_TOKEN` keys. Region can also be set, but it is not mandatory when using AWS.
These can be set as environment variables or passed in the `storage_options` parameter:
=== "Python"
```python
import lancedb
db = await lancedb.connect_async(
"s3://bucket/path",
storage_options={
"aws_access_key_id": "my-access-key",
"aws_secret_access_key": "my-secret-key",
"aws_session_token": "my-session-token",
}
)
```

```ts
import * as lancedb from "@lancedb/lancedb";
const db = await lancedb.connect(
"s3://bucket/path",
{
storageOptions: {
awsAccessKeyId: "my-access-key",
awsSecretAccessKey: "my-secret-key",
awsSessionToken: "my-session-token",
}
}
);
```
=== "vectordb (deprecated)"
```ts
const lancedb = require("lancedb");
const db = await lancedb.connect(
"s3://bucket/path",
{
storageOptions: {
awsAccessKeyId: "my-access-key",
awsSecretAccessKey: "my-secret-key",
awsSessionToken: "my-session-token",
}
}
);
```
To configure credentials for AWS S3, you can use the `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and `AWS_SESSION_TOKEN` environment variables.
Alternatively, if you are using AWS SSO, you can use the `AWS_PROFILE` and `AWS_DEFAULT_REGION` environment variables.
The following keys can be used as both environment variables or keys in the `storage_options` parameter:
| Key | Description |
|------------------------------------|------------------------------------------------------------------------------------------------------|
| `aws_region` / `region` | The AWS region the bucket is in. This can be automatically detected when using AWS S3, but must be specified for S3-compatible stores. |
| `aws_access_key_id` / `access_key_id` | The AWS access key ID to use. |
| `aws_secret_access_key` / `secret_access_key` | The AWS secret access key to use. |
| `aws_session_token` / `session_token` | The AWS session token to use. |
| `aws_endpoint` / `endpoint` | The endpoint to use for S3-compatible stores. |
| `aws_virtual_hosted_style_request` / `virtual_hosted_style_request` | Whether to use virtual hosted-style requests, where the bucket name is part of the endpoint. Meant to be used with `aws_endpoint`. Default: `False`. |
| `aws_s3_express` / `s3_express` | Whether to use S3 Express One Zone endpoints. Default: `False`. See more details below. |
| `aws_server_side_encryption` | The server-side encryption algorithm to use. Must be one of `"AES256"`, `"aws:kms"`, or `"aws:kms:dsse"`. Default: `None`. |
| `aws_sse_kms_key_id` | The KMS key ID to use for server-side encryption. If set, `aws_server_side_encryption` must be `"aws:kms"` or `"aws:kms:dsse"`. |
| `aws_sse_bucket_key_enabled` | Whether to use bucket keys for server-side encryption. |

}
```
#### DynamoDB Commit Store for concurrent writes
By default, S3 does not support concurrent writes. Having two or more processes
writing to the same table at the same time can lead to data corruption. This is
because S3, unlike other object stores, does not have any atomic put or copy
operation.
To enable concurrent writes, you can configure LanceDB to use a DynamoDB table
as a commit store. This table will be used to coordinate writes between
different processes. To enable this feature, you must modify your connection
URI to use the `s3+ddb` scheme and add a query parameter `ddbTableName` with the
name of the table to use.
=== "Python"
```python
import lancedb
db = await lancedb.connect_async(
"s3+ddb://bucket/path?ddbTableName=my-dynamodb-table",
)
```
=== "JavaScript"
```javascript
const lancedb = require("lancedb");
const db = await lancedb.connect(
"s3+ddb://bucket/path?ddbTableName=my-dynamodb-table",
);
```
The DynamoDB table must be created with the following schema:
- Hash key: `base_uri` (string)
- Range key: `version` (number)
You can create this programmatically with:
=== "Python"
<!-- skip-test -->
```python
import boto3
dynamodb = boto3.client("dynamodb")

endpoint: "http://minio:9000",
}
}
);
```
This can also be done with the ``AWS_ENDPOINT`` and ``AWS_DEFAULT_REGION`` environment variables.
!!! tip "Local servers"
For local development, the server often has a `http` endpoint rather than a
secure `https` endpoint. In this case, you must also set the `ALLOW_HTTP`
environment variable to `true` to allow non-TLS connections, or pass the
storage option `allow_http` as `true`. If you do not do this, you will get
an error like `URL scheme is not allowed`.
#### S3 Express
LanceDB supports [S3 Express One Zone](https://aws.amazon.com/s3/storage-classes/express-one-zone/) endpoints, but requires additional configuration. Also, S3 Express endpoints only support connecting from an EC2 instance within the same region.
To configure LanceDB to use an S3 Express endpoint, you must set the storage option `s3_express`. The bucket name in your table URI should **include the suffix**.
=== "Python"
```python
import lancedb
db = await lancedb.connect_async(

## Improving retriever performance
Try it yourself - <a href="https://colab.research.google.com/github/lancedb/lancedb/blob/main/docs/src/notebooks/lancedb_reranking.ipynb"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"></a><br/>
VectorDBs are used as retreivers in recommender or chatbot-based systems for retrieving relevant data based on user queries. For example, retriever is a critical component of Retrieval Augmented Generation (RAG) acrhitectures. In this section, we will discuss how to improve the performance of retrievers.
There are serveral ways to improve the performance of retrievers. Some of the common techniques are:
* Using different query types
* Using hybrid search
* Fine-tuning the embedding models
* Using different embedding models
Using different embedding models is something that's very specific to the use case and the data. So we will not discuss it here. In this section, we will discuss the first three techniques.
!!! note "Note"
We'll be using a simple metric called "hit-rate" for evaluating the performance of the retriever across this guide. Hit-rate is the percentage of queries for which the retriever returned the correct answer in the top-k results. For example, if the retriever returned the correct answer in the top-3 results for 70% of the queries, then the hit-rate@3 is 0.7.
## The dataset
We'll be using a QA dataset generated using a LLama2 review paper. The dataset contains 221 query, context and answer triplets. The queries and answers are generated using GPT-4 based on a given query. Full script used to generate the dataset can be found on this [repo](https://github.com/lancedb/ragged). It can be downloaded from [here](https://github.com/AyushExel/assets/blob/main/data_qa.csv)
### Using different query types
Let's setup the embeddings and the dataset first. We'll use the LanceDB's `huggingface` embeddings integration for this guide.
```python
import lancedb
import pandas as pd
from lancedb.embeddings import get_registry
from lancedb.pydantic import Vector, LanceModel
db = lancedb.connect("~/lancedb/query_types")
df = pd.read_csv("data_qa.csv")
embed_fcn = get_registry().get("huggingface").create(name="BAAI/bge-small-en-v1.")
class Schema(LanceModel):
context: str = embed_fcn.SourceField()
vector: Vector(embed_fcn.ndims()) = embed_fcn.VectorField()
table = db.create_table("qa", schema=Schema)
table.add(df[["context"]].to_dict(orient="records"))
queries = df["query"].tolist()
```
Now that we have the dataset and embeddings table set up, here's how you can run different query types on the dataset.
* <b> Vector Search: </b>
```python
table.search(quries[0], query_type="vector").limit(5).to_pandas()
```
By default, LanceDB uses vector search query type for searching and it automatically converts the input query to a vector before searching when using embedding API. So, the following statement is equivalent to the above statement.
```python
table.search(quries[0]).limit(5).to_pandas()
```
Vector or semantic search is useful when you want to find documents that are similar to the query in terms of meaning.
---
* <b> Full-text Search: </b>
FTS requires creating an index on the column you want to search on. `replace=True` will replace the existing index if it exists.
Once the index is created, you can search using the `fts` query type.
```python
table.create_fts_index("context", replace=True)
table.search(quries[0], query_type="fts").limit(5).to_pandas()
```
Full-text search is useful when you want to find documents that contain the query terms.
---
* <b> Hybrid Search: </b>
Hybrid search is a combination of vector and full-text search. Here's how you can run a hybrid search query on the dataset.
```python
table.search(quries[0], query_type="hybrid").limit(5).to_pandas()
```
Hybrid search requires a reranker to combine and rank the results from vector and full-text search. We'll cover reranking as a concept in the next section.
Hybrid search is useful when you want to combine the benefits of both vector and full-text search.
!!! note "Note"
By default, it uses `LinearCombinationReranker` that combines the scores from vector and full-text search using a weighted linear combination. It is the simplest reranker implementation available in LanceDB. You can also use other rerankers like `CrossEncoderReranker` or `CohereReranker` for reranking the results.
Learn more about rerankers [here](https://lancedb.github.io/lancedb/reranking/)
### Hit rate evaluation results
Now that we have seen how to run different query types on the dataset, let's evaluate the hit-rate of each query type on the dataset.
For brevity, the entire evaluation script is not shown here. You can find the complete evaluation and benchmarking utility scripts [here](https://github.com/lancedb/ragged).
Here are the hit-rate results for the dataset:
| Query Type | Hit-rate@5 |
| --- | --- |
| Vector Search | 0.640 |
| Full-text Search | 0.595 |
| Hybrid Search (w/ LinearCombinationReranker) | 0.645 |
**Choosing query type** is very specific to the use case and the data. This synthetic dataset has been generated to be semantically challenging, i.e, the queries don't have a lot of keywords in common with the context. So, vector search performs better than full-text search. However, in real-world scenarios, full-text search might perform better than vector search. Hybrid search is a good choice when you want to combine the benefits of both vector and full-text search.
### Evaluation results on other datasets
The hit-rate results can vary based on the dataset and the query type. Here are the hit-rate results for the other datasets using the same embedding function.
* <b> SQuAD Dataset: </b>
| Query Type | Hit-rate@5 |
| --- | --- |
| Vector Search | 0.822 |
| Full-text Search | 0.835 |
| Hybrid Search (w/ LinearCombinationReranker) | 0.8874 |
* <b> Uber10K sec filing Dataset: </b>
| Query Type | Hit-rate@5 |
| --- | --- |
| Vector Search | 0.608 |
| Full-text Search | 0.82 |
| Hybrid Search (w/ LinearCombinationReranker) | 0.80 |
In these standard datasets, FTS seems to perform much better than vector search because the queries have a lot of keywords in common with the context. So, in general choosing the query type is very specific to the use case and the data.

Continuing from the previous section, we can now rerank the results using more complex rerankers.
Try it yourself - <a href="https://colab.research.google.com/github/lancedb/lancedb/blob/main/docs/src/notebooks/lancedb_reranking.ipynb"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"></a><br/>
## Reranking search results
You can rerank any search results using a reranker. The syntax for reranking is as follows:
```python
from lancedb.rerankers import LinearCombinationReranker
reranker = LinearCombinationReranker()
table.search(quries[0], query_type="hybrid").rerank(reranker=reranker).limit(5).to_pandas()
```
Based on the `query_type`, the `rerank()` function can accept other arguments as well. For example, hybrid search accepts a `normalize` param to determine the score normalization method.
!!! note "Note"
LanceDB provides a `Reranker` base class that can be extended to implement custom rerankers. Each reranker must implement the `rerank_hybrid` method. `rerank_vector` and `rerank_fts` methods are optional. For example, the `LinearCombinationReranker` only implements the `rerank_hybrid` method and so it can only be used for reranking hybrid search results.
## Choosing a Reranker
There are many rerankers available in LanceDB like `CrossEncoderReranker`, `CohereReranker`, and `ColBERT`. The choice of reranker depends on the dataset and the application. You can even implement you own custom reranker by extending the `Reranker` class. For more details about each available reranker and performance comparison, refer to the [rerankers](https://lancedb.github.io/lancedb/reranking/) documentation.
In this example, we'll use the `CohereReranker` to rerank the search results. It requires `cohere` to be installed and `COHERE_API_KEY` to be set in the environment. To get your API key, sign up on [Cohere](https://cohere.ai/).
```python
from lancedb.rerankers import CohereReranker
# use Cohere reranker v3
reranker = CohereReranker(model_name="rerank-english-v3.0") # default model is "rerank-english-v2.0"
```
### Reranking search results
Now we can rerank all query type results using the `CohereReranker`:
```python
# rerank hybrid search results
table.search(quries[0], query_type="hybrid").rerank(reranker=reranker).limit(5).to_pandas()
# rerank vector search results
table.search(quries[0], query_type="vector").rerank(reranker=reranker).limit(5).to_pandas()
# rerank fts search results
table.search(quries[0], query_type="fts").rerank(reranker=reranker).limit(5).to_pandas()
```
Each reranker can accept additional arguments. For example, `CohereReranker` accepts `top_k` and `batch_size` params to control the number of documents to rerank and the batch size for reranking respectively. Similarly, a custom reranker can accept any number of arguments based on the implementation. For example, a reranker can accept a `filter` that implements some custom logic to filter out documents before reranking.
## Results
Let us take a look at the same datasets from the previous sections, using the same embedding table but with Cohere reranker applied to all query types.
!!! note "Note"
When reranking fts or vector search results, the search results are over-fetched by a factor of 2 and then reranked. From the reranked set, `top_k` (5 in this case) results are taken. This is done because reranking will have no effect on the hit-rate if we only fetch the `top_k` results.

## Finetuning the Embedding Model
Try it yourself - <a href="https://colab.research.google.com/github/lancedb/lancedb/blob/main/docs/src/notebooks/embedding_tuner.ipynb"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"></a><br/>
Another way to improve retriever performance is to fine-tune the embedding model itself. Fine-tuning the embedding model can help in learning better representations for the documents and queries in the dataset. This can be particularly useful when the dataset is very different from the pre-trained data used to train the embedding model.
We'll use the same dataset as in the previous sections. Start off by splitting the dataset into training and validation sets:
```python
from sklearn.model_selection import train_test_split
train_df, validation_df = train_test_split("data_qa.csv", test_size=0.2, random_state=42)
train_df.to_csv("data_train.csv", index=False)
validation_df.to_csv("data_val.csv", index=False)
```
You can use any tuning API to fine-tune embedding models. In this example, we'll utilise Llama-index as it also comes with utilities for synthetic data generation and training the model.
Then parse the dataset as llama-index text nodes and generate synthetic QA pairs from each node.
```python
from llama_index.core.node_parser import SentenceSplitter
from llama_index.readers.file import PagedCSVReader
from llama_index.finetuning import generate_qa_embedding_pairs
from llama_index.core.evaluation import EmbeddingQAFinetuneDataset
def load_corpus(file):
loader = PagedCSVReader(encoding="utf-8")
docs = loader.load_data(file=Path(file))
parser = SentenceSplitter()
nodes = parser.get_nodes_from_documents(docs)
return nodes
from llama_index.llms.openai import OpenAI

llm=OpenAI(model="gpt-3.5-turbo"), nodes=train_nodes, verbose=False
)
val_dataset = generate_qa_embedding_pairs(
llm=OpenAI(model="gpt-3.5-turbo"), nodes=val_nodes, verbose=False
)
```
Now we'll use `SentenceTransformersFinetuneEngine` engine to fine-tune the model. You can also use `sentence-transformers` or `transformers` library to fine-tune the model.
```python
from llama_index.finetuning import SentenceTransformersFinetuneEngine
finetune_engine = SentenceTransformersFinetuneEngine(
train_dataset,
model_id="BAAI/bge-small-en-v1.5",
model_output_path="tuned_model",
val_dataset=val_dataset,
)
finetune_engine.finetune()
embed_model = finetune_engine.get_finetuned_model()
```
This saves the fine tuned embedding model in `tuned_model` folder. This al
# Evaluation results
In order to eval the retriever, you can either use this model to ingest the data into LanceDB directly or llama-index's LanceDB integration to create a `VectorStoreIndex` and use it as a retriever.

## The challenge of (re)ranking search results
Once you have a group of the most relevant search results from multiple search sources, you'd likely standardize the score and rank them accordingly. This process can also be seen as another independent step-reranking.
There are two approaches for reranking search results from multiple sources.
* <b>Score-based</b>: Calculate final relevance scores based on a weighted linear combination of individual search algorithm scores. Example-Weighted linear combination of semantic search & keyword-based search results.
* <b>Relevance-based</b>: Discards the existing scores and calculates the relevance of each search result-query pair. Example-Cross Encoder models
Even though there are many strategies for reranking search results, none works for all cases. Moreover, evaluating them itself is a challenge. Also, reranking can be dataset, application specific so it's hard to generalize.

# dlt
[dlt](https://dlthub.com/docs/intro) is an open-source library that you can add to your Python scripts to load data from various and often messy data sources into well-structured, live datasets. dlt's [integration with LanceDB](https://dlthub.com/docs/dlt-ecosystem/destinations/lancedb) lets you ingest data from any source (databases, APIs, CSVs, dataframes, JSONs, and more) into LanceDB with a few lines of simple python code. The integration enables automatic normalization of nested data, schema inference, incremental loading and embedding the data. dlt also has integrations with several other tools like dbt, airflow, dagster etc. that can be inserted into your LanceDB workflow.
## How to ingest data into LanceDB
In this example, we will be fetching movie information from the [Open Movie Database (OMDb) API](https://www.omdbapi.com/) and loading it into a local LanceDB instance. To implement it, you will need an API key for the OMDb API (which can be created freely [here](https://www.omdbapi.com/apikey.aspx)).
1. **Install `dlt` with LanceDB extras:**
```sh
pip install dlt[lancedb]
```
2. **Inside an empty directory, initialize a `dlt` project with:**
```sh
dlt init rest_api lancedb
```
This will add all the files necessary to create a `dlt` pipeline that can ingest data from any REST API (ex: OMDb API) and load into LanceDB.
```text
├── .dlt
│ ├── config.toml
│ └── secrets.toml
├── rest_api
├── rest_api_pipeline.py
└── requirements.txt
```
dlt has a list of pre-built [sources](https://dlthub.com/docs/dlt-ecosystem/verified-sources/) like [SQL databases](https://dlthub.com/docs/dlt-ecosystem/verified-sources/sql_database), [REST APIs](https://dlthub.com/docs/dlt-ecosystem/verified-sources/rest_api), [Google Sheets](https://dlthub.com/docs/dlt-ecosystem/verified-sources/google_sheets), [Notion](https://dlthub.com/docs/dlt-ecosystem/verified-sources/notion) etc., that can be used out-of-the-box by running `dlt init <source_name> lancedb`. Since dlt is a python library, it is also very easy to modify these pre-built sources or to write your own custom source from scratch.
3. **Specify necessary credentials and/or embedding model details:**
In order to fetch data from the OMDb API, you will need to pass a valid API key into your pipeline. Depending on whether you're using LanceDB OSS or LanceDB cloud, you also may need to provide the necessary credentials to connect to the LanceDB instance. These can be pasted inside `.dlt/sercrets.toml`.
dlt's LanceDB integration also allows you to automatically embed the data during ingestion. Depending on the embedding model chosen, you may need to paste the necessary credentials inside `.dlt/sercrets.toml`:
```toml
[sources.rest_api]
api_key = "api_key" # Enter the API key for the OMDb API
[destination.lancedb]
embedding_model_provider = "sentence-transformers"
embedding_model = "all-MiniLM-L6-v2"
[destination.lancedb.credentials]
uri = ".lancedb"
api_key = "api_key" # API key to connect to LanceDB Cloud. Leave out if you are using LanceDB OSS.
embedding_model_provider_api_key = "embedding_model_provider_api_key" # Not needed for providers that don't need authentication (ollama, sentence-transformers).
```

4. **Write the pipeline code inside `rest_api_pipeline.py`:**
The following code shows how you can configure dlt's REST API source to connect to the [OMDb API](https://www.omdbapi.com/), fetch all movies with the word "godzilla" in the title, and load it into a LanceDB table. The REST API source allows you to pull data from any API with minimal code, to learn more read the [dlt docs](https://dlthub.com/docs/dlt-ecosystem/verified-sources/rest_api).
```python
# Import necessary modules
import dlt
from rest_api import rest_api_source
# Configure the REST API source
movies_source = rest_api_source(
{
"client": {
"base_url": "https://www.omdbapi.com/",
"auth": { # authentication strategy for the OMDb API
"type": "api_key",
"name": "apikey",
"api_key": dlt.secrets["sources.rest_api.api_token"], # read API credentials directly from secrets.toml
"location": "query"
},
"paginator": { # pagination strategy for the OMDb API
"type": "page_number",
"base_page": 1,
"total_path": "totalResults",
"maximum_page": 5
}
},
"resources": [ # list of API endpoints to request
{
"name": "movie_search",
"endpoint": {
"path": "/",
"params": {
"s": "godzilla",
"type": "movie"
}
}
}
]
})
if __name__ == "__main__":
# Create a pipeline object
pipeline = dlt.pipeline(
pipeline_name='movies_pipeline',
destination='lancedb', # this tells dlt to load the data into LanceDB
dataset_name='movies_data_pipeline',
)
# Run the pipeline
load_info = pipeline.run(movies_source)
# pretty print the information on data that was loaded
print(load_info)
```
The script above will ingest the data into LanceDB as it is, i.e. without creating any embeddings. If we want to embed one of the fields (for example, `"Title"` that contains the movie titles), then we will use dlt's `lancedb_adapter` and modify the script as follows:
- Add the following import statement:
```python
from dlt.destinations.adapters import lancedb_adapter
```
- Modify the pipeline run like this:
```python
load_info = pipeline.run(
lancedb_adapter(
movies_source,
embed="Title",
)
)
```
This will use the embedding model specified inside `.dlt/secrets.toml` to embed the field `"Title"`.
5. **Install necessary dependencies:**
```sh
pip install -r requirements.txt
```
Note: You may need to install the dependencies for your embedding models separately.
```sh
pip install sentence-transformers
```
6. **Run the pipeline:**
Finally, running the following command will ingest the data into your LanceDB instance.
```sh
python custom_source.py
```
For more information and advanced usage of dlt's LanceDB integration, read [the dlt documentation](https://dlthub.com/docs/dlt-ecosystem/destinations/lancedb).

# Langchain
![Illustration](../assets/langchain.png)
## Quick Start
You can load your document data using langchain's loaders, for this example we are using `TextLoader` and `OpenAIEmbeddings` as the embedding model. Checkout Complete example here - [LangChain demo](../notebooks/langchain_example.ipynb)
```python
import os
from langchain.document_loaders import TextLoader
from langchain.vectorstores import LanceDB
from langchain_openai import OpenAIEmbeddings
from langchain_text_splitters import CharacterTextSplitter
os.environ["OPENAI_API_KEY"] = "sk-..."
loader = TextLoader("../../modules/state_of_the_union.txt") # Replace with your data path
documents = loader.load()
documents = CharacterTextSplitter().split_documents(documents)
embeddings = OpenAIEmbeddings()
docsearch = LanceDB.from_documents(documents, embeddings)
query = "What did the president say about Ketanji Brown Jackson"
docs = docsearch.similarity_search(query)
print(docs[0].page_content)
```
## Documentation
In the above example `LanceDB` vector store class object is created using `from_documents()` method which is a `classmethod` and returns the initialized class object.
You can also use `LanceDB.from_texts(texts: List[str],embedding: Embeddings)` class method.
The exhaustive list of parameters for `LanceDB` vector store are :
- `connection`: (Optional) `lancedb.db.LanceDBConnection` connection object to use. If not provided, a new connection will be created.
- `embedding`: Langchain embedding model.
- `vector_key`: (Optional) Column name to use for vector's in the table. Defaults to `'vector'`.
- `id_key`: (Optional) Column name to use for id's in the table. Defaults to `'id'`.
- `text_key`: (Optional) Column name to use for text in the table. Defaults to `'text'`.
- `table_name`: (Optional) Name of your table in the database. Defaults to `'vectorstore'`.
- `api_key`: (Optional) API key to use for LanceDB cloud database. Defaults to `None`.
- `region`: (Optional) Region to use for LanceDB cloud database. Only for LanceDB Cloud, defaults to `None`.
- `mode`: (Optional) Mode to use for adding data to the table. Defaults to `'overwrite'`.
- `reranker`: (Optional) The reranker to use for LanceDB.
- `relevance_score_fn`: (Optional[Callable[[float], float]]) Langchain relevance score function to be used. Defaults to `None`.
```python
db_url = "db://lang_test" # url of db you created
api_key = "xxxxx" # your API key
region="us-east-1-dev" # your selected region
vector_store = LanceDB(
uri=db_url,
api_key=api_key, #(dont include for local API)
region=region, #(dont include for local API)
embedding=embeddings,
table_name='langchain_test' #Optional
)
```
### Methods
##### add_texts()
- `texts`: `Iterable` of strings to add to the vectorstore.
- `metadatas`: Optional `list[dict()]` of metadatas associated with the texts.
- `ids`: Optional `list` of ids to associate with the texts.
- `kwargs`: `Any`
This method adds texts and stores respective embeddings automatically.
```python
vector_store.add_texts(texts = ['test_123'], metadatas =[{'source' :'wiki'}])
#Additionaly, to explore the table you can load it into a df or save it in a csv file:
tbl = vector_store.get_table()
print("tbl:", tbl)
pd_df = tbl.to_pandas()
pd_df.to_csv("docsearch.csv", index=False)
# you can also create a new vector store object using an older connection object:
vector_store = LanceDB(connection=tbl, embedding=embeddings)
```
##### create_index()
- `col_name`: `Optional[str] = None`
- `vector_col`: `Optional[str] = None`
- `num_partitions`: `Optional[int] = 256`
- `num_sub_vectors`: `Optional[int] = 96`
- `index_cache_size`: `Optional[int] = None`
This method creates an index for the vector store. For index creation make sure your table has enough data in it. An ANN index is ususally not needed for datasets ~100K vectors. For large-scale (>1M) or higher dimension vectors, it is beneficial to create an ANN index.
```python
# for creating vector index
vector_store.create_index(vector_col='vector', metric = 'cosine')
# for creating scalar index(for non-vector columns)
vector_store.create_index(col_name='text')
```
##### similarity_search()
- `query`: `str`
- `k`: `Optional[int] = None`
- `filter`: `Optional[Dict[str, str]] = None`
- `fts`: `Optional[bool] = False`
- `name`: `Optional[str] = None`
- `kwargs`: `Any`
Return documents most similar to the query without relevance scores
```python
docs = docsearch.similarity_search(query)
print(docs[0].page_content)
```
##### similarity_search_by_vector()
- `embedding`: `List[float]`
- `k`: `Optional[int] = None`
- `filter`: `Optional[Dict[str, str]] = None`
- `name`: `Optional[str] = None`
- `kwargs`: `Any`
Returns documents most similar to the query vector.
```python
docs = docsearch.similarity_search_by_vector(query)
print(docs[0].page_content)
```
##### similarity_search_with_score()
- `query`: `str`
- `k`: `Optional[int] = None`
- `filter`: `Optional[Dict[str, str]] = None`
- `kwargs`: `Any`
Returns documents most similar to the query string with relevance scores, gets called by base class's `similarity_search_with_relevance_scores` which selects relevance score based on our `_select_relevance_score_fn`.
```python
docs = docsearch.similarity_search_with_relevance_scores(query)
print("relevance score - ", docs[0][1])
print("text- ", docs[0][0].page_content[:1000])
```
##### similarity_search_by_vector_with_relevance_scores()
- `embedding`: `List[float]`
- `k`: `Optional[int] = None`
- `filter`: `Optional[Dict[str, str]] = None`
- `name`: `Optional[str] = None`
- `kwargs`: `Any`
Return documents most similar to the query vector with relevance scores.
Relevance score
```python
docs = docsearch.similarity_search_by_vector_with_relevance_scores(query_embedding)
print("relevance score - ", docs[0][1])
print("text- ", docs[0][0].page_content[:1000])
```
##### max_marginal_relevance_search()
- `query`: `str`
- `k`: `Optional[int] = None`
- `fetch_k` : Number of Documents to fetch to pass to MMR algorithm, `Optional[int] = None`
- `lambda_mult`: Number between 0 and 1 that determines the degree
of diversity among the results with 0 corresponding
to maximum diversity and 1 to minimum diversity.
Defaults to 0.5. `float = 0.5`
- `filter`: `Optional[Dict[str, str]] = None`
- `kwargs`: `Any`
Returns docs selected using the maximal marginal relevance(MMR).
Maximal marginal relevance optimizes for similarity to query AND diversity among selected documents.
Similarly, `max_marginal_relevance_search_by_vector()` function returns docs most similar to the embedding passed to the function using MMR. instead of a string query you need to pass the embedding to be searched for.
```python
result = docsearch.max_marginal_relevance_search(
query="text"
)
result_texts = [doc.page_content for doc in result]
print(result_texts)
## search by vector :
result = docsearch.max_marginal_relevance_search_by_vector(
embeddings.embed_query("text")
)
result_texts = [doc.page_content for doc in result]
print(result_texts)
```
##### add_images()
- `uris` : File path to the image. `List[str]`.
- `metadatas` : Optional list of metadatas. `(Optional[List[dict]], optional)`
- `ids` : Optional list of IDs. `(Optional[List[str]], optional)`
Adds images by automatically creating their embeddings and adds them to the vectorstore.
```python
vec_store.add_images(uris=image_uris)
# here image_uris are local fs paths to the images.
```

# Llama-Index
![Illustration](../assets/llama-index.jpg)
## Quick start
You would need to install the integration via `pip install llama-index-vector-stores-lancedb` in order to use it.
You can run the below script to try it out :
```python
import logging
import sys
# Uncomment to see debug logs
# logging.basicConfig(stream=sys.stdout, level=logging.DEBUG)
# logging.getLogger().addHandler(logging.StreamHandler(stream=sys.stdout))
from llama_index.core import SimpleDirectoryReader, Document, StorageContext
from llama_index.core import VectorStoreIndex
from llama_index.vector_stores.lancedb import LanceDBVectorStore
import textwrap
import openai
openai.api_key = "sk-..."
documents = SimpleDirectoryReader("./data/your-data-dir/").load_data()
print("Document ID:", documents[0].doc_id, "Document Hash:", documents[0].hash)
## For LanceDB cloud :
# vector_store = LanceDBVectorStore(
# uri="db://db_name", # your remote DB URI
# api_key="sk_..", # lancedb cloud api key
# region="your-region" # the region you configured
# ...
# )
vector_store = LanceDBVectorStore(
uri="./lancedb", mode="overwrite", query_type="vector"
)
storage_context = StorageContext.from_defaults(vector_store=vector_store)
index = VectorStoreIndex.from_documents(
documents, storage_context=storage_context
)
lance_filter = "metadata.file_name = 'paul_graham_essay.txt' "
retriever = index.as_retriever(vector_store_kwargs={"where": lance_filter})
response = retriever.retrieve("What did the author do growing up?")
```
Checkout Complete example here - [LlamaIndex demo](../notebooks/LlamaIndex_example.ipynb)
### Filtering
For metadata filtering, you can use a Lance SQL-like string filter as demonstrated in the example above. Additionally, you can also filter using the `MetadataFilters` class from LlamaIndex:
```python
from llama_index.core.vector_stores import (
MetadataFilters,
FilterOperator,
FilterCondition,
MetadataFilter,
)
query_filters = MetadataFilters(
filters=[
MetadataFilter(
key="creation_date", operator=FilterOperator.EQ, value="2024-05-23"
),
MetadataFilter(
key="file_size", value=75040, operator=FilterOperator.GT
),
],
condition=FilterCondition.AND,
)
```
### Hybrid Search
For complete documentation, refer [here](https://lancedb.github.io/lancedb/hybrid_search/hybrid_search/). This example uses the `colbert` reranker. Make sure to install necessary dependencies for the reranker you choose.
```python
from lancedb.rerankers import ColbertReranker
reranker = ColbertReranker()
vector_store._add_reranker(reranker)
query_engine = index.as_query_engine(
filters=query_filters,
vector_store_kwargs={
"query_type": "hybrid",
}
)
response = query_engine.query("How much did Viaweb charge per month?")
```
In the above snippet, you can change/specify query_type again when creating the engine/retriever.

### Running lint / format
LanceDb uses [biome](https://biomejs.dev/) for linting and formatting. if you are using VSCode you will need to install the official [Biome](https://marketplace.visualstudio.com/items?itemName=biomejs.biome) extension.
To manually lint your code you can run:
LanceDb uses eslint for linting. VSCode does not need any plugins to use eslint. However, it
may need some additional configuration. Make sure that eslint.experimental.useFlatConfig is
set to true. Also, if your vscode root folder is the repo root then you will need to set
the eslint.workingDirectories to ["nodejs"]. To manually lint your code you can run:
```sh
npm run lint
```
to automatically fix all fixable issues:
LanceDb uses prettier for formatting. If you are using VSCode you will need to install the
"Prettier - Code formatter" extension. You should then configure it to be the default formatter
for typescript and you should enable format on save. To manually check your code's format you
can run:
```sh
npm run lint-fix
npm run chkformat
```
If you do not have your workspace root set to the `nodejs` directory, unfortunately the extension will not work. You can still run the linting and formatting commands manually.
If you need to manually format your code you can run:
```sh
npx prettier --write .

Checks out a specific version of the table _This is an in-place operation._
### checkout
This allows viewing previous versions of the table. If you wish to
keep writing to the dataset starting from an old version, then use
the `restore` function.
**checkout**(`version`): `Promise`\<`void`\>
Calling this method will set the table into time-travel mode. If you
wish to return to standard mode, call `checkoutLatest`.
Checks out a specific version of the Table
Any read operation on the table will now access the data at the checked out version.
As a consequence, calling this method will disable any read consistency interval
that was previously set.
This is a read-only operation that turns the table into a sort of "view"
or "detached head". Other table instances will not be affected. To make the change
permanent you can use the `[Self::restore]` method.
Any operation that modifies the table will fail while the table is in a checked
out state.
To return the table to a normal state use `[Self::checkout_latest]`
#### Parameters

### optimize()
> `abstract` **optimize**(`options`?): `Promise`&lt;`OptimizeStats`&gt;
Optimize the on-disk data and indices for better performance.
Modeled after ``VACUUM`` in PostgreSQL.
Optimization covers three operations:
- Compaction: Merges small files into larger ones
- Prune: Removes old versions of the dataset
- Index: Optimizes the indices, adding new data to existing indices
Experimental API
----------------
The optimization process is undergoing active development and may change.
Our goal with these changes is to improve the performance of optimization and
reduce the complexity.
That being said, it is essential today to run optimize if you want the best
performance. It should be stable and safe to use in production, but it our
hope that the API may be simplified (or not even need to be called) in the
future.
The frequency an application shoudl call optimize is based on the frequency of
data modifications. If data is frequently added, deleted, or updated then
optimize should be run frequently. A good rule of thumb is to run optimize if
you have added or modified 100,000 or more records or run more than 20 data
modification operations.
#### Parameters
