Most of the time, setting nprobes to cover 5-10% of the dataset should achieve high recall with low latency.<br/>
|
||||
e.g., for 1M vectors divided up into 256 partitions, nprobes should be set to ~20-40.<br/>
|
||||
Note: nprobes is only applicable if an ANN index is present. If specified on a table without an ANN index, it is ignored.
|
||||
Most of the time, setting nprobes to cover 5-15% of the dataset should achieve high recall with low latency.<br/>
|
||||
- _For example_, For a dataset of 1 million vectors divided into 256 partitions, `nprobes` should be set to ~20-40. This value can be adjusted to achieve the optimal balance between search latency and search quality. <br/>
|
||||
|
||||
- **refine_factor** (default: None): Refine the results by reading extra elements and re-ranking them in memory.<br/>
|
||||
A higher number makes search more accurate but also slower. If you find the recall is less than ideal, try refine_factor=10 to start.<br/>
|
||||
e.g., for 1M vectors divided into 256 partitions, if you're looking for top 20, then refine_factor=200 reranks the whole partition.<br/>
|
||||
Note: refine_factor is only applicable if an ANN index is present. If specified on a table without an ANN index, it is ignored.
|
||||
- _For example_, For a dataset of 1 million vectors divided into 256 partitions, setting the `refine_factor` to 200 will initially retrieve the top 4,000 candidates (top k * refine_factor) from all searched partitions. These candidates are then reranked to determine the final top 20 results.<br/>
|
||||
!!! note
|
||||
Both `nprobes` and `refine_factor` are only applicable if an ANN index is present. If specified on a table without an ANN index, those parameters are ignored.

# VoyageAI Embeddings
|
||||
|
||||
Voyage AI provides cutting-edge embedding and rerankers.
|
||||
|
||||
|
||||
Using voyageai API requires voyageai package, which can be installed using `pip install voyageai`. Voyage AI 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 `VOYAGE_API_KEY` environment variable to use the VoyageAI API.
|
||||
|
||||
Supported models are:
|
||||
|
||||
- voyage-3
|
||||
- voyage-3-lite
|
||||
- voyage-finance-2
|
||||
- voyage-multilingual-2
|
||||
- voyage-law-2
|
||||
- voyage-code-2
|
||||
|
||||
|
||||
Supported parameters (to be passed in `create` method) are:
|
||||
|
||||
| Parameter | Type | Default Value | Description |
|
||||
|---|---|--------|---------|
|
||||
| `name` | `str` | `"voyage-3"` | The model ID of the model to use. Supported base models for Text Embeddings: voyage-3, voyage-3-lite, voyage-finance-2, voyage-multilingual-2, voyage-law-2, voyage-code-2 |
|
||||
| `input_type` | `str` | `None` | Type of the input text. Default to None. Other options: query, document. |
|
||||
| `truncation` | `bool` | `True` | Whether to truncate the input texts to fit within the context length. |
|
||||
|
||||
|
||||
Usage Example:
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
from lancedb.pydantic import LanceModel, Vector
|
||||
from lancedb.embeddings import EmbeddingFunctionRegistry

# Full-text search (Native FTS)

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.
|
||||
|
||||
Currently, the Lance full text search is missing some features that are in the Tantivy full text search. This includes query parser 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.
|
||||

||||
|
||||
## Installation (Only for Tantivy-based FTS)

LanceDB provides support for full-text search via Lance, allowing you to incorporate keyword-based search (based on BM25) in your retrieval solutions.
|

# Say you want to use tantivy==0.20.1

|

!!! 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".
|
||||
By default the text is tokenized by splitting on punctuation and whitespaces, and would filter out words that are with length greater than 40, and lowercase all words.
|
||||
|
||||
For now, only the Tantivy-based FTS index supports to specify the tokenizer, so it's only available in Python with `use_tantivy=True`.
|
||||
|
||||
=== "use_tantivy=True"
|
||||
Stemming is useful for improving search results by reducing words to their root form, e.g. "running" to "run". LanceDB supports stemming for multiple languages, you can specify the tokenizer name to enable stemming by the pattern `tokenizer_name="{language_code}_stem"`, e.g. `en_stem` for English.
|
||||
|
||||
For example, to enable stemming for English:
|
||||
```python
|
||||
table.create_fts_index("text", use_tantivy=True, tokenizer_name="en_stem")
|
||||
```
|
||||
|
||||
=== "use_tantivy=False"
|
||||
|
||||
[**Not supported yet**](https://github.com/lancedb/lance/issues/1195)
|
||||
|
||||
the following [languages](https://docs.rs/tantivy/latest/tantivy/tokenizer/enum.Language.html) are currently supported.
|
||||
|
||||
## Index multiple columns
|
||||
|
||||
If you have multiple string columns to index, there's no need to combine them manually -- simply pass them all as a list to `create_fts_index`:
|
||||
|
||||
=== "use_tantivy=True"
|
||||
The tokenizer is customizable, you can specify how the tokenizer splits the text, and how it filters out words, etc.
|
||||
|
||||
For example, for language with accents, you can specify the tokenizer to use `ascii_folding` to remove accents, e.g. 'é' to 'e':
|
||||
```python
|
||||
table.create_fts_index(["text1", "text2"])
|
||||
table.create_fts_index("text",
|
||||
use_tantivy=False,

Note that the search API call does not change - you can search over all indexed columns at once.
|

|
||||
## Filtering
|

## Sorting
|

|

!!! warning "Warn"
|
||||
Sorting is available for only Tantivy-based FTS
|
||||
|
||||
You can pre-sort the documents by specifying `ordering_field_names` when
|
||||
creating the full-text search index. Once pre-sorted, you can then specify
|
||||
`ordering_field_name` while searching to return results sorted by the given
|

field. For example,
|
||||
|

error will be raised that looks like `ValueError: The field does not exist: xxx`
|

The fields to sort on must be of typed unsigned integer, or else you will see
|
||||
an error during indexing that looks like
|
||||
`TypeError: argument 'value': 'float' object cannot be interpreted as an integer`.
|
||||
|
||||
!!! note
|
||||
You can specify multiple fields for ordering at indexing time.
|
||||
But at query time only one ordering field is supported.
|
||||
|
||||
|
||||
## Phrase queries vs. terms queries
|
||||
|
||||
!!! warning "Warn"
|
||||
Lance-based FTS doesn't support queries using boolean operators `OR`, `AND`.
|
||||
|
||||
For full-text search you can specify either a **phrase** query like `"the old man and the sea"`,
|
||||
or a **terms** search query like `"(Old AND Man) AND Sea"`. For more details on the terms
|
||||
or a **terms** search query like `old man sea`. For more details on the terms
|
||||
query syntax, see Tantivy's [query parser rules](https://docs.rs/tantivy/latest/tantivy/query/struct.QueryParser.html).
|
||||
|
||||
!!! tip "Note"
|
||||
The query parser will raise an exception on queries that are ambiguous. For example, in the query `they could have been dogs OR cats`, `OR` is capitalized so it's considered a keyword query operator. But it's ambiguous how the left part should be treated. So if you submit this search query as is, you'll get `Syntax Error: they could have been dogs OR cats`.
|
||||
|
||||
```py
|
||||
# This raises a syntax error
|
||||
table.search("they could have been dogs OR cats")
|
||||
```
|
||||
|
||||
On the other hand, lowercasing `OR` to `or` will work, because there are no capitalized logical operators and
|
||||
the query is treated as a phrase query.
|
||||
|
||||
```py
|
||||
# This works!
|
||||
table.search("they could have been dogs or cats")
|
||||
```
|
||||
|
||||
It can be cumbersome to have to remember what will cause a syntax error depending on the type of
|
||||
query you want to perform. To make this simpler, when you want to perform a phrase query, you can
|
||||
enforce it in one of two ways:
|
||||
|
||||
1. Place the double-quoted query inside single quotes. For example, `table.search('"they could have been dogs OR cats"')` is treated as
|
||||
a phrase query.
|
||||
1. Explicitly declare the `phrase_query()` method. This is useful when you have a phrase query that
|
||||
itself contains double quotes. For example, `table.search('the cats OR dogs were not really "pets" at all').phrase_query()`
|
||||
is treated as a phrase query.
|
||||
|
||||
In general, a query that's declared as a phrase query will be wrapped in double quotes during parsing, with nested
|
||||
double quotes replaced by single quotes.
|
||||
|
||||
|
||||
## Configurations (Only for Tantivy-based FTS)
|
||||
|
||||
By default, LanceDB configures a 1GB heap size limit for creating the index. You can
|
||||
reduce this if running on a smaller node, or increase this for faster performance while
|
||||
indexing a larger corpus.
|
||||
|
||||
To search for a phrase, the index must be created with `with_position=True`:
|
||||
```python
|
||||
# configure a 512MB heap size
|
||||
heap = 1024 * 1024 * 512
|
||||
table.create_fts_index(["text1", "text2"], writer_heap_size=heap, replace=True)
|
||||
table.create_fts_index("text", use_tantivy=False, with_position=True)
|
||||
```
|
||||
|
||||
## Current limitations
|
||||
|
||||
For that Tantivy-based FTS:
|
||||
|
||||
1. Currently we do not yet support incremental writes.
|
||||
If you add data after FTS index creation, it won't be reflected
|
||||
in search results until you do a full reindex.
|
||||
|
||||
2. We currently only support local filesystem paths for the FTS index.
|
||||
This is a tantivy limitation. We've implemented an object store plugin
|
||||
but there's no way in tantivy-py to specify to use it.
|
||||
This will allow you to search for phrases, but it will also significantly increase the index size and indexing time.

# Full-text search (Tantivy-based FTS)

||||
|
||||
LanceDB also provides support for full-text search via [Tantivy](https://github.com/quickwit-oss/tantivy), allowing you to incorporate keyword-based search (based on BM25) in your retrieval solutions.
|
||||
|
||||
The tantivy-based FTS is only available in Python and does not support building indexes on object storage or incremental indexing. If you need these features, try native FTS [native FTS](fts.md).
|
||||
|
||||
## Installation
|
||||
|
||||
To use full-text search, install the dependency [`tantivy-py`](https://github.com/quickwit-oss/tantivy-py):
|
||||
|
||||
```sh
|
||||
# Say you want to use tantivy==0.20.1
|
||||
pip install tantivy==0.20.1
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
Consider that we have a LanceDB table named `my_table`, whose string column `content` we want to index and query via keyword search, the FTS index must be created before you can search via keywords.
|
||||
|
||||
```python
|
||||
import lancedb
|
||||
|
||||
uri = "data/sample-lancedb"
|
||||
db = lancedb.connect(uri)
|
||||
|
||||
table = db.create_table(
|
||||
"my_table",
|
||||
data=[
|
||||
{"id": 1, "vector": [3.1, 4.1], "title": "happy puppy", "content": "Frodo was a happy puppy", "meta": "foo"},
|
||||
{"id": 2, "vector": [5.9, 26.5], "title": "playing kittens", "content": "There are several kittens playing around the puppy", "meta": "bar"},
|
||||
],
|
||||
)
|
||||
|
||||
# passing `use_tantivy=False` to use lance FTS index
|
||||
# `use_tantivy=True` by default
|
||||
table.create_fts_index("content", use_tantivy=True)
|
||||
table.search("puppy").limit(10).select(["content"]).to_list()
|
||||
# [{'text': 'Frodo was a happy puppy', '_score': 0.6931471824645996}]
|
||||
# ...
|
||||
```

||||
|
||||
It would search on all indexed columns by default, so it's useful when there are multiple indexed columns.
|
||||
|
||||
!!! note

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".
|
||||
|
||||
```python
|
||||
table.create_fts_index("content", use_tantivy=True, tokenizer_name="en_stem", replace=True)

```
|
||||
|
||||
the following [languages](https://docs.rs/tantivy/latest/tantivy/tokenizer/enum.Language.html) are currently supported.
|
||||
|
||||
## Index multiple columns
|
||||
|
||||
If you have multiple string columns to index, there's no need to combine them manually -- simply pass them all as a list to `create_fts_index`:

```python

|
||||
```
|
||||
|
||||
Note that the search API call does not change - you can search over all indexed columns at once.
|
||||
|
||||
## Filtering
|
||||
|
||||
Currently the LanceDB full text search feature supports *post-filtering*, meaning filters are
|
||||
applied on top of the full text search results (see [native FTS](fts.md) if you need pre-filtering). This can be invoked via the familiar
|

||||
|
||||
```python
|
||||

|
||||
```
|
||||
|
||||
## Sorting
|
||||
|
||||
You can pre-sort the documents by specifying `ordering_field_names` when
|
||||
creating the full-text search index. Once pre-sorted, you can then specify
|
||||
`ordering_field_name` while searching to return results sorted by the given
|
||||
field. For example,
|
||||
|
||||
```python
|
||||
table.create_fts_index(["content"], use_tantivy=True, ordering_field_names=["id"], replace=True)
|
||||
|
||||
(table.search("puppy", ordering_field_name="id")
|
||||
.limit(20)
|
||||
.to_list())
|
||||
```
|
||||
|
||||
!!! note
|
||||
If you wish to specify an ordering field at query time, you must also
|
||||
have specified it during indexing time. Otherwise at query time, an
|
||||
error will be raised that looks like `ValueError: The field does not exist: xxx`
|
||||
|
||||

|
||||
The fields to sort on must be of typed unsigned integer, or else you will see
|
||||
an error during indexing that looks like
|
||||
`TypeError: argument 'value': 'float' object cannot be interpreted as an integer`.
|
||||
|
||||
!!! note
|
||||
You can specify multiple fields for ordering at indexing time.
|
||||
But at query time only one ordering field is supported.
|
||||
|
||||
|
||||
## Phrase queries vs. terms queries
|
||||
|
||||
For full-text search you can specify either a **phrase** query like `"the old man and the sea"`,
|
||||
or a **terms** search query like `"(Old AND Man) AND Sea"`. For more details on the terms
|
||||
query syntax, see Tantivy's [query parser rules](https://docs.rs/tantivy/latest/tantivy/query/struct.QueryParser.html).
|

## Handling bad vectors
|
||||
|
||||
In LanceDB Python, you can use the `on_bad_vectors` parameter to choose how
|
||||
invalid vector values are handled. Invalid vectors are vectors that are not valid
|
||||
because:
|
||||
|
||||
1. They are the wrong dimension
|
||||
2. They contain NaN values
|
||||
3. They are null but are on a non-nullable field
|
||||
|
||||
By default, LanceDB will raise an error if it encounters a bad vector. You can
|
||||
also choose one of the following options:
|
||||
|
||||
* `drop`: Ignore rows with bad vectors
|
||||
* `fill`: Replace bad values (NaNs) or missing values (too few dimensions) with
|
||||
the fill value specified in the `fill_value` parameter. An input like
|
||||
`[1.0, NaN, 3.0]` will be replaced with `[1.0, 0.0, 3.0]` if `fill_value=0.0`.
|
||||
* `null`: Replace bad vectors with null (only works if the column is nullable).
|
||||
A bad vector `[1.0, NaN, 3.0]` will be replaced with `null` if the column is
|
||||
nullable. If the vector column is non-nullable, then bad vectors will cause an

error

# Langchain
|
||||

|
||||
**LangChain** is a framework designed for building applications with large language models (LLMs) by chaining together various components. It supports a range of functionalities including memory, agents, and chat models, enabling developers to create context-aware applications.
|
||||
|
||||

|
||||
|
||||
LangChain streamlines these stages (in figure above) by providing pre-built components and tools for integration, memory management, and deployment, allowing developers to focus on application logic rather than underlying complexities.
|
||||
|
||||
Integration of **Langchain** with **LanceDB** enables applications to retrieve the most relevant data by comparing query vectors against stored vectors, facilitating effective information retrieval. It results in better and context aware replies and actions by the LLMs.
|
||||
|
||||
## 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)

### mergeInsert
|
||||
|
||||
▸ **mergeInsert**(`on`, `data`, `args`): `Promise`\<`void`\>
|
||||
|
||||
Runs a "merge insert" operation on the table
|
||||
|
||||
This operation can add rows, update rows, and remove rows all in a single
|
||||
transaction. It is a very generic tool that can be used to create
|
||||
behaviors like "insert if not exists", "update or insert (i.e. upsert)",
|
||||
or even replace a portion of existing data with new data (e.g. replace
|
||||
all data where month="january")
|
||||
|
||||
The merge insert operation works by combining new data from a
|
||||
**source table** with existing data in a **target table** by using a
|
||||
join. There are three categories of records.
|
||||
|
||||
"Matched" records are records that exist in both the source table and
|
||||
the target table. "Not matched" records exist only in the source table
|
||||
(e.g. these are new data) "Not matched by source" records exist only
|
||||
in the target table (this is old data)
|
||||
|
||||
The MergeInsertArgs can be used to customize what should happen for
|
||||
each category of data.
|
||||
|
||||
Please note that the data may appear to be reordered as part of this
|
||||
operation. This is because updated rows will be deleted from the
|
||||
dataset and then reinserted at the end with the new values.
|
||||
|
||||
#### Parameters
|
||||
|
||||
| Name | Type | Description |
|
||||
| :------ | :------ | :------ |
|
||||
| `on` | `string` | a column to join on. This is how records from the source table and target table are matched. |

updates to the table from other processes. If None, then consistency is not
|
||||
checked. For performance reasons, this is the default. For strong
|
||||
consistency, set this to zero seconds. Then every read will check for
|
||||
updates from other processes. As a compromise, you can set this to a
|
||||
non-zero value for eventual consistency. If more than that interval
|
||||
has passed since the last check, then the table will be checked for updates.
|
||||
Note: this consistency only applies to read operations. Write operations are
|
||||
always consistent.

|

|

• `Optional` **whenMatchedUpdateAll**: `string` \| `boolean`
|
||||
|
||||
If true then rows that exist in both the source table (new data) and
|
||||
the target table (old data) will be updated, replacing the old row
|
||||
with the corresponding matching row.
|
||||
|
||||
If there are multiple matches then the behavior is undefined.
|
||||
Currently this causes multiple copies of the row to be created
|
||||
but that behavior is subject to change.
|
||||
|
||||
Optionally, a filter can be specified. This should be an SQL
|
||||
filter where fields with the prefix "target." refer to fields
|
||||
in the target table (old data) and fields with the prefix
|
||||
"source." refer to fields in the source table (new data). For
|
||||
example, the filter "target.lastUpdated < source.lastUpdated" will
|
||||
only update matched rows when the incoming `lastUpdated` value is
|
||||
newer.
|
||||
|
||||
Rows that do not match the filter will not be updated. Rows that
|
||||
do not match the filter do become "not matched" rows.

If true then rows that exist only in the target table (old data)
|
||||
will be deleted.
|
||||
|
||||
If this is a string then it will be treated as an SQL filter and
|
||||
only rows that both do not match any row in the source table and
|
||||
match the given filter will be deleted.
|
||||
|
||||
This can be used to replace a selection of existing data with

new data.

|
||||
|
||||
#### Type declaration
|
||||
|
||||
▸ (`on`, `data`, `args`): `Promise`\<`void`\>
|
||||
|
||||
Runs a "merge insert" operation on the table
|
||||
|
||||
This operation can add rows, update rows, and remove rows all in a single
|
||||
transaction. It is a very generic tool that can be used to create
|
||||
behaviors like "insert if not exists", "update or insert (i.e. upsert)",
|
||||
or even replace a portion of existing data with new data (e.g. replace
|
||||
all data where month="january")
|
||||
|
||||
The merge insert operation works by combining new data from a
|
||||
**source table** with existing data in a **target table** by using a
|
||||
join. There are three categories of records.
|
||||
|
||||
"Matched" records are records that exist in both the source table and
|
||||
the target table. "Not matched" records exist only in the source table
|
||||
(e.g. these are new data) "Not matched by source" records exist only
|
||||
in the target table (this is old data)
|
||||
|
||||
The MergeInsertArgs can be used to customize what should happen for
|
||||
each category of data.
|
||||
|
||||
Please note that the data may appear to be reordered as part of this
|
||||
operation. This is because updated rows will be deleted from the
|
||||
dataset and then reinserted at the end with the new values.

### makeArrowTable
|
||||
|
||||
▸ **makeArrowTable**(`data`, `options?`): `ArrowTable`
|
||||
|
||||
An enhanced version of the makeTable function from Apache Arrow
|
||||
that supports nested fields and embeddings columns.
|
||||
|
||||
This function converts an array of Record<String, any> (row-major JS objects)
|
||||
to an Arrow Table (a columnar structure)
|
||||
|
||||
Note that it currently does not support nulls.
|
||||
|
||||
If a schema is provided then it will be used to determine the resulting array
|
||||
types. Fields will also be reordered to fit the order defined by the schema.
|
||||
|
||||
If a schema is not provided then the types will be inferred and the field order
|
||||
will be controlled by the order of properties in the first record.
|
||||
|
||||
If the input is empty then a schema must be provided to create an empty table.
|
||||
|
||||
When a schema is not specified then data types will be inferred. The inference
|
||||
rules are as follows:
|
||||
|
||||
- boolean => Bool
|
||||
- number => Float64
|
||||
- String => Utf8
|
||||
- Buffer => Binary
|
||||
- Record<String, any> => Struct
|
||||
- Array<any> => List
|
||||
|
||||
#### Parameters
|
||||
|
||||
| Name | Type | Description |
|
||||
| :------ | :------ | :------ |
|
||||
| `data` | `Record`\<`string`, `any`\>[] | input data |
|
||||
| `options?` | `Partial`\<[`MakeArrowTableOptions`](classes/MakeArrowTableOptions.md)\> | options to control the makeArrowTable call. |
|
||||
|
||||
#### Returns
|
||||
|
||||
`ArrowTable`
|
||||
|
||||
**`Example`**
|
||||
|
||||
```ts
|
||||
|
||||
import { fromTableToBuffer, makeArrowTable } from "../arrow";
|
||||
import { Field, FixedSizeList, Float16, Float32, Int32, Schema } from "apache-arrow";
|
||||
|
||||
const schema = new Schema([
|
||||
new Field("a", new Int32()),
|
||||
new Field("b", new Float32()),
|
||||
new Field("c", new FixedSizeList(3, new Field("item", new Float16()))),
|
||||
]);
|
||||
const table = makeArrowTable([
|
||||
{ a: 1, b: 2, c: [1, 2, 3] },
|
||||
{ a: 4, b: 5, c: [4, 5, 6] },
|
||||
{ a: 7, b: 8, c: [7, 8, 9] },
|
||||
], { schema });
|
||||
```
|
||||
|
||||
By default it assumes that the column named `vector` is a vector column
|
||||
and it will be converted into a fixed size list array of type float32.
|
||||
The `vectorColumns` option can be used to support other vector column
|
||||
names and data types.
|
||||
|
||||
```ts
|
||||
|
||||
const schema = new Schema([
|
||||
new Field("a", new Float64()),
|
||||
new Field("b", new Float64()),
|
||||
new Field(
|
||||
"vector",
|
||||
new FixedSizeList(3, new Field("item", new Float32()))
|
||||
),
|
||||
]);
|
||||
const table = makeArrowTable([
|
||||
{ a: 1, b: 2, vector: [1, 2, 3] },
|
||||
{ a: 4, b: 5, vector: [4, 5, 6] },
|
||||
{ a: 7, b: 8, vector: [7, 8, 9] },
|
||||
]);
|
||||
assert.deepEqual(table.schema, schema);
|
||||
```
|
||||
|
||||
You can specify the vector column types and names using the options as well
|
||||
|
||||
```typescript
|
||||
|
||||
const schema = new Schema([
|
||||
new Field('a', new Float64()),
|
||||
new Field('b', new Float64()),
|
||||
new Field('vec1', new FixedSizeList(3, new Field('item', new Float16()))),
|
||||
new Field('vec2', new FixedSizeList(3, new Field('item', new Float16())))
|
||||
]);
|
||||
const table = makeArrowTable([
|
||||
{ a: 1, b: 2, vec1: [1, 2, 3], vec2: [2, 4, 6] },
|
||||
{ a: 4, b: 5, vec1: [4, 5, 6], vec2: [8, 10, 12] },
|
||||
{ a: 7, b: 8, vec1: [7, 8, 9], vec2: [14, 16, 18] }
|
||||
], {
|
||||
vectorColumns: {
|
||||
vec1: { type: new Float16() },
|
||||
vec2: { type: new Float16() }
|
||||
}
|
||||
}

If this is true then the index will store the positions of the term in the document.

This allows phrase queries to be run. But it also increases the size of the index,

and the time to build the index.

# Voyage AI Reranker
|
||||
|
||||
Voyage AI provides cutting-edge embedding and rerankers.
|
||||
|
||||
This re-ranker uses the [VoyageAI](https://docs.voyageai.com/docs/) API to rerank the search results. You can use this re-ranker by passing `VoyageAIReranker()` to the `rerank()` method. Note that you'll either need to set the `VOYAGE_API_KEY` environment variable or pass the `api_key` argument to use this re-ranker.
|
||||
|
||||
|
||||
!!! note
|
||||
Supported Query Types: Hybrid, Vector, FTS

## Getting help
|
||||
|
||||
The following sections provide various diagnostics and troubleshooting tips for LanceDB.
|
||||
These can help you provide additional information when asking questions or making
|
||||
error reports.
|
||||
|
||||
For trouble shooting, the best place to ask is in our Discord, under the relevant
|
||||
language channel. By asking in the language-specific channel, it makes it more
|
||||
likely that someone who knows the answer will see your question.
|
||||
|
||||
## Enabling logging
|
||||
|
||||
To provide more information, especially for LanceDB Cloud related issues, enable
|
||||
debug logging. You can set the `LANCEDB_LOG` environment variable:
|
||||
|
||||
```shell
|
||||
export LANCEDB_LOG=debug
|
||||
```
|
||||
|
||||
You can turn off colors and formatting in the logs by setting
|
||||
|
||||
```shell
|
||||
export LANCEDB_LOG_STYLE=never
|
||||
```
|
||||
|
||||
## Explaining query plans
|
||||
|
||||
If you have slow queries or unexpected query results, it can be helpful to
|
||||
print the resolved query plan. You can use the `explain_plan` method to do this:
|
||||
|
||||
* Python Sync: [LanceQueryBuilder.explain_plan][lancedb.query.LanceQueryBuilder.explain_plan]
|
||||
* Python Async: [AsyncQueryBase.explain_plan][lancedb.query.AsyncQueryBase.explain_plan]
|
||||
* Node @lancedb/lancedb: [LanceQueryBuilder.explainPlan](/lancedb/js/classes/QueryBase/#explainplan)
