LanceDB provides many parameters to fine-tune the index's size, the speed of queries, and the accuracy of results.

|
|
||||||
## Disk-based Index
|
Currently, LanceDB does *not* automatically create the ANN index.
|
||||||
|
LanceDB has optimized code for kNN as well. For many use-cases, datasets under 100K vectors won't require index creation at all.
|
||||||
|
If you can live with <100ms latency, skipping index creation is a simpler workflow while guaranteeing 100% recall.

the dataset into `N` partitions, and then applies **Product Quantization** to compress vectors in each partition.
|
|
||||||
See the [indexing](concepts/index_ivfpq.md) concepts guide for more information on how this works.
|
## Types of Index
|
||||||
|
|
||||||
|
Lance can support multiple index types, the most widely used one is `IVF_PQ`.
|
||||||
|
|
||||||
|
* `IVF_PQ`: use **Inverted File Index (IVF)** to first divide the dataset into `N` partitions,
|
||||||
|
and then use **Product Quantization** to compress vectors in each partition.
|
||||||
|
* `DiskANN` (**Experimental**): organize the vector as a on-disk graph, where the vertices approximately
|
||||||
|
represent the nearest neighbors of each vector.

### Why do I need to manually create an index?
|
|
||||||
|
|

Currently, LanceDB does _not_ automatically create the ANN index.

LanceDB is well-optimized for kNN (exhaustive search) via a disk-based index. For many use-cases,

datasets of the order of ~100K vectors don't require index creation. If you can live with up to

100ms latency, skipping index creation is a simpler workflow while guaranteeing 100% recall.

By default, LanceDB runs a brute-force scan over dataset to find the K nearest neighbours (KNN).
|
|
||||||
For tables with more than 50K vectors, creating an ANN index is recommended to speed up search performance.
|
|
||||||
LanceDB allows you to create an ANN index on a table as follows:
|
|
||||||
|
|
||||||
=== "Python"
|
|
||||||
|
|
||||||
```py
|
|
||||||
tbl.create_index()
|
|
||||||
```
|
|
||||||
|
|
||||||
=== "Typescript"
|
|
||||||
|
|
||||||
```{.typescript .ignore}
|

||||||
|
|
||||||
```rust
|
|
||||||
--8<-- "rust/lancedb/examples/simple.rs:create_index"
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! note "Why do I need to create an index manually?"
|
|
||||||
LanceDB does not automatically create the ANN index, for two reasons. The first is that it's optimized
|
|
||||||
for really fast retrievals via a disk-based index, and the second is that data and query workloads can
|
|
||||||
be very diverse, so there's no one-size-fits-all index configuration. LanceDB provides many parameters
|
|
||||||
to fine-tune index size, query latency and accuracy. See the section on
|
|
||||||
[ANN indexes](ann_indexes.md) for more details.

|

|
### When is it necessary to create a vector index?
|
||||||
|
|
||||||
|
LanceDB has manually-tuned SIMD code for computing vector distances. In our benchmarks, computing 100K pairs of 1K dimension vectors takes **<20ms**. For small datasets (<100K rows) or applications that can accept up to 100ms latency, vector indices are usually not necessary.

|
||||||
|
For large-scale or higher dimension vectors, it is beneficial to create vector index.
|
||||||
|
|
||||||
|
### How big is my index, and how much memory will it take?
|
||||||
|
|
||||||
|
In LanceDB, all vector indices are disk-based, meaning that when responding to a vector query, only the relevant pages from the index file are loaded from disk and cached in memory. Additionally, each sub-vector is usually encoded into 1 byte PQ code.
|
||||||
|
|
||||||
|
For example, with 1024-dimension vectors, if we choose `num_sub_vectors = 64`, each sub-vector has `1024 / 64 = 16` float32 numbers. Product quantization can lead to approximately `16 * sizeof(float32) / 1 = 64` times of space reduction.
|
||||||
|
|
||||||
|
### How to choose `num_partitions` and `num_sub_vectors` for IVF_PQ index?
|
||||||
|
|
||||||
|
`num_partitions` is used to decide how many partitions the first level IVF index uses. Higher number of partitions could lead to more efficient I/O during queries and better accuracy, but it takes much more time to train. On SIFT-1M dataset, our benchmark shows that keeping each partition 1K-4K rows lead to a good latency/recall.
|
||||||
|
|
||||||
|
`num_sub_vectors` specifies how many PQ short codes to generate on each vector. Because PQ is a lossy compression of the original vector, a higher `num_sub_vectors` usually results in less space distortion, and thus yields better accuracy. However, a higher `num_sub_vectors` also causes heavier I/O and more PQ computation, and thus, higher latency. `dimension / num_sub_vectors` should be a multiple of 8 for optimum SIMD efficiency.

The most popular open source option is to use the [sentence-transformers](https://www.sbert.net/)
|

|
library, which can be installed via pip.
|
||||||
|
|
||||||

```bash

## Applying an embedding function to data
|
||||||
|
|
||||||
|
=== "Python"
|
||||||
|
Using an embedding function, you can apply it to raw data
|
||||||
|
to generate embeddings for each record.
|
||||||
|
|
||||||
|
Say you have a pandas DataFrame with a `text` column that you want embedded,
|
||||||
|
you can use the `with_embeddings` function to generate embeddings and add them to
|
||||||
|
an existing table.
|
||||||
|
|
||||||
|
```python
|
||||||
|
import pandas as pd
|
||||||
|
from lancedb.embeddings import with_embeddings
|
||||||
|
|
||||||
|
df = pd.DataFrame(
|
||||||
|
[
|
||||||
|
{"text": "pepperoni"},
|
||||||
|
{"text": "pineapple"}
|
||||||
|
]
|
||||||
|
)
|
||||||
|
data = with_embeddings(embed_func, df)
|
||||||
|
|
||||||
|
# The output is used to create / append to a table
|
||||||
|
# db.create_table("my_table", data=data)
|
||||||
|
```
|
||||||
|
|
||||||
|
If your data is in a different column, you can specify the `column` kwarg to `with_embeddings`.
|
||||||
|
|
||||||
|
By default, LanceDB calls the function with batches of 1000 rows. This can be configured
|
||||||
|
using the `batch_size` parameter to `with_embeddings`.
|
||||||
|
|
||||||
|
LanceDB automatically wraps the function with retry and rate-limit logic to ensure the OpenAI
|
||||||
|
API call is reliable.

|
|
||||||
|
!!! warning

||||||
|
At query time, you **must** use the same embedding function you used to vectorize your data.
|
||||||
|

space and the results will be nonsensical.

The embedding function defined above abstracts away all the details about the models and dimensions required to define the schema. You can simply set a field as **source** or **vector** column. Here's how:

`VectorField` tells LanceDB to use the clip embedding function to generate query embeddings for the `vector` column and `SourceField` ensures that when adding data, we automatically use the specified embedding function to encode `image_uri`.
|
## 3. Create LanceDB table
|
||||||
|
Now that we have chosen/defined our embedding function and the schema, we can create the table:
|
||||||
|
|
||||||
=== "JavaScript"
|
```python
|
||||||
|
db = lancedb.connect("~/lancedb")
|
||||||
|
table = db.create_table("pets", schema=Pets)
|
||||||
|
|
||||||
For the TypeScript SDK, a schema can be inferred from input data, or an explicit
|
```
|
||||||
Arrow schema can be provided.
|
|
||||||
|
|
||||||
## 3. Create table and add data
|
That's it! We've provided all the information needed to embed the source and query inputs. We can now forget about the model and dimension details and start to build our VectorDB pipeline.
|
||||||
|
|
||||||
Now that we have chosen/defined our embedding function and the schema,
|
## 4. Ingest lots of data and query your table
|
||||||
we can create the table and ingest data without needing to explicitly generate
|
Any new or incoming data can just be added and it'll be vectorized automatically.
|
||||||
the embeddings at all:
|
|
||||||
|
|
||||||
=== "Python"
|
```python
|
||||||
```python
|
table.add([{"image_uri": u} for u in uris])
|
||||||
db = lancedb.connect("~/lancedb")
|
```
|
||||||
table = db.create_table("pets", schema=Pets)
|
|
||||||
|
|
||||||
table.add([{"image_uri": u} for u in uris])
|
Our OpenCLIP query embedding function supports querying via both text and images:
|
||||||
```
|
|
||||||
|
|
||||||
=== "JavaScript"
|
```python
|
||||||
|
result = table.search("dog")
|
||||||
|
```
|
||||||
|
|
||||||
```javascript
|
Let's query an image:
|
||||||
const db = await lancedb.connect("data/sample-lancedb");
|
|
||||||
const data = [
|
|
||||||
{ text: "pepperoni"},
|
|
||||||
{ text: "pineapple"}
|
|
||||||

|
|
||||||
|
|

|
||||||
```
|
p = Path("path/to/images/samoyed_100.jpg")
|
||||||
|
query_image = Image.open(p)
|
||||||

|
|
||||||

|
|
||||||
.to_pandas()
|
|
||||||
)
|
|
||||||
```
|
|
||||||
|
|
||||||
Or we can search using an image:
|
|
||||||
|
|
||||||
```python
|
|
||||||
p = Path("path/to/images/samoyed_100.jpg")
|
|
||||||
query_image = Image.open(p)
|
|
||||||

|
|
||||||
.limit(10)
|
|
||||||
.to_pandas()
|
|
||||||
)
|
|
||||||
```
|
|
||||||
|
|
||||||
Both of the above snippet returns a pandas DataFrame with the 10 closest vectors to the query.
|
|
||||||
|
|
||||||

||||||
|
|
||||||
```javascript
|
|
||||||
const results = await table

.search("What's the best pizza topping?")

.limit(10)

|

2. You can use the built-in [embedding functions](./embedding_functions.md) to embed the data and queries in the background.

### Hugging Face
|
|
||||||
|
|
||||||
The most popular open source option is to use the [sentence-transformers](https://www.sbert.net/)
|
|
||||||
library, which can be installed via pip.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
pip install sentence-transformers
|
|
||||||
```
|
|
||||||
|
|
||||||
The example below shows how to use the `paraphrase-albert-small-v2` model to generate embeddings
|
|
||||||
for a given document.
|
|
||||||
|
|
||||||
```python
|
|
||||||
from sentence_transformers import SentenceTransformer
|
|
||||||
|
|
||||||
name="paraphrase-albert-small-v2"
|
|
||||||
model = SentenceTransformer(name)
|
|
||||||
|
|
||||||
# used for both training and querying
|
|
||||||
def embed_func(batch):
|
|
||||||
return [model.encode(sentence) for sentence in batch]
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
### OpenAI
|
|
||||||
|
|
||||||
Another popular alternative is to use an external API like OpenAI's [embeddings API](https://platform.openai.com/docs/guides/embeddings/what-are-embeddings).
|
|
||||||
|
|
||||||
```python
|
|
||||||
import openai
|
|
||||||
import os
|
|
||||||
|
|
||||||
# Configuring the environment variable OPENAI_API_KEY
|
|
||||||
if "OPENAI_API_KEY" not in os.environ:
|
|
||||||
# OR set the key here as a variable
|
|
||||||
openai.api_key = "sk-..."
|
|
||||||
|
|
||||||
client = openai.OpenAI()
|
|
||||||
|
|
||||||
def embed_func(c):
|
|
||||||
rs = client.embeddings.create(input=c, model="text-embedding-ada-002")
|
|
||||||
return [record.embedding for record in rs["data"]]
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
## Applying an embedding function to data
|
|
||||||
|
|
||||||
Using an embedding function, you can apply it to raw data
|
|
||||||
to generate embeddings for each record.
|
|
||||||
|
|
||||||
Say you have a pandas DataFrame with a `text` column that you want embedded,
|
|
||||||
you can use the `with_embeddings` function to generate embeddings and add them to
|
|
||||||
an existing table.
|
|
||||||
|
|
||||||
```python
|
|
||||||
import pandas as pd
|
|
||||||
from lancedb.embeddings import with_embeddings
|
|
||||||
|
|
||||||
df = pd.DataFrame(
|
|
||||||
[
|
|
||||||
{"text": "pepperoni"},
|
|
||||||
{"text": "pineapple"}
|
|
||||||
]
|
|
||||||
)
|
|
||||||
data = with_embeddings(embed_func, df)
|
|
||||||
|
|
||||||
# The output is used to create / append to a table
|
|
||||||
tbl = db.create_table("my_table", data=data)
|
|
||||||
```
|
|
||||||
|
|
||||||
If your data is in a different column, you can specify the `column` kwarg to `with_embeddings`.
|
|
||||||
|
|
||||||
By default, LanceDB calls the function with batches of 1000 rows. This can be configured
|
|
||||||
using the `batch_size` parameter to `with_embeddings`.
|
|
||||||
|
|
||||||
LanceDB automatically wraps the function with retry and rate-limit logic to ensure the OpenAI
|
|
||||||
API call is reliable.
|
|
||||||
|
|
||||||
## Querying using an embedding function
|
|
||||||
|
|
||||||
!!! warning
|
|
||||||
At query time, you **must** use the same embedding function you used to vectorize your data.
|
|
||||||
If you use a different embedding function, the embeddings will not reside in the same vector
|
|
||||||
space and the results will be nonsensical.
|
|
||||||
|
|
||||||
=== "Python"
|
|
||||||
```python
|
|
||||||
query = "What's the best pizza topping?"
|
|
||||||
query_vector = embed_func([query])[0]
|
|
||||||
results = (

|
Double quotes are used to disambiguate.
|
||||||
|
|
||||||
!!! tip "Note"
|
For example:
|
||||||
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
|
If you intended "they could have been dogs OR cats" as a phrase query, this actually
|
||||||
# This raises a syntax error
|
raises a syntax error since `OR` is a recognized operator. If you make `or` lower case,
|
||||||
table.search("they could have been dogs OR cats")
|
this avoids the syntax error. However, it is cumbersome to have to remember what will
|
||||||
```
|
conflict with the query syntax. Instead, if you search using
|
||||||
|
`table.search('"they could have been dogs OR cats"')`, then the syntax checker avoids
|
||||||
|
checking inside the quotes.
|
||||||
|
|
||||||
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.
|
|
||||||
2. 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.

!!! tip "Automatic cleanup for failed writes"
|
|
||||||
|
|
||||||
LanceDB uses [multi-part uploads](https://docs.aws.amazon.com/AmazonS3/latest/userguide/mpuoverview.html) when writing data to S3 in order to maximize write speed. LanceDB will abort these uploads when it shuts down gracefully, such as when cancelled by keyboard interrupt. However, in the rare case that LanceDB crashes, it is possible that some data will be left lingering in your account. To cleanup this data, we recommend (as AWS themselves do) that you setup a lifecycle rule to delete in-progress uploads after 7 days. See the AWS guide:
|
|
||||||
|
|
||||||
**[Configuring a bucket lifecycle configuration to delete incomplete multipart uploads](https://docs.aws.amazon.com/AmazonS3/latest/userguide/mpu-abort-incomplete-mpu-lifecycle-config.html)**
|
|
||||||
|
|
||||||
#### AWS IAM Permissions
|
|
||||||
|
|
||||||
If a bucket is private, then an IAM policy must be specified to allow access to it. For many development scenarios, using broad permissions such as a PowerUser account is more than sufficient for working with LanceDB. However, in many production scenarios, you may wish to have as narrow as possible permissions.
|
|
||||||
|
|
||||||
For **read and write access**, LanceDB will need a policy such as:

## Consistency
|
|
||||||
|
|
||||||
In LanceDB OSS, users can set the `read_consistency_interval` parameter on connections to achieve different levels of read consistency. This parameter determines how frequently the database synchronizes with the underlying storage system to check for updates made by other processes. If another process updates a table, the database will not see the changes until the next synchronization.
|
|
||||||
|
|
||||||
There are three possible settings for `read_consistency_interval`:
|
|
||||||
|
|
||||||
1. **Unset (default)**: The database does not check for updates to tables made by other processes. This provides the best query performance, but means that clients may not see the most up-to-date data. This setting is suitable for applications where the data does not change during the lifetime of the table reference.
|
|
||||||
2. **Zero seconds (Strong consistency)**: The database checks for updates on every read. This provides the strongest consistency guarantees, ensuring that all clients see the latest committed data. However, it has the most overhead. This setting is suitable when consistency matters more than having high QPS.
|
|
||||||
3. **Custom interval (Eventual consistency)**: The database checks for updates at a custom interval, such as every 5 seconds. This provides eventual consistency, allowing for some lag between write and read operations. Performance wise, this is a middle ground between strong consistency and no consistency check. This setting is suitable for applications where immediate consistency is not critical, but clients should see updated data eventually.
|
|
||||||
|
|
||||||
!!! tip "Consistency in LanceDB Cloud"
|
|
||||||
|
|
||||||
This is only tune-able in LanceDB OSS. In LanceDB Cloud, readers are always eventually consistent.
|
|
||||||
|
|
||||||
=== "Python"
|
|
||||||
|
|
||||||
To set strong consistency, use `timedelta(0)`:
|
|
||||||
|
|
||||||
```python
|
|
||||||
from datetime import timedelta
|
|
||||||
db = lancedb.connect("./.lancedb",. read_consistency_interval=timedelta(0))
|
|
||||||
table = db.open_table("my_table")
|
|
||||||
```
|
|
||||||
|
|
||||||
For eventual consistency, use a custom `timedelta`:
|
|
||||||
|
|
||||||
```python
|
|
||||||
from datetime import timedelta
|
|
||||||
db = lancedb.connect("./.lancedb", read_consistency_interval=timedelta(seconds=5))
|
|
||||||
table = db.open_table("my_table")
|
|
||||||
```
|
|
||||||
|
|
||||||
By default, a `Table` will never check for updates from other writers. To manually check for updates you can use `checkout_latest`:
|
|
||||||
|
|
||||||
```python
|
|
||||||
db = lancedb.connect("./.lancedb")
|
|
||||||
table = db.open_table("my_table")
|
|
||||||
|
|
||||||
# (Other writes happen to my_table from another process)
|
|
||||||
|
|
||||||
# Check for updates
|
|
||||||
table.checkout_latest()
|
|
||||||
```
|
|
||||||
|
|
||||||
=== "JavaScript/Typescript"
|
|
||||||
|
|
||||||
To set strong consistency, use `0`:
|
|
||||||
|
|
||||||
```javascript
|
|
||||||
const db = await lancedb.connect({ uri: "./.lancedb", readConsistencyInterval: 0 });
|
|
||||||
const table = await db.openTable("my_table");
|
|
||||||
```
|
|
||||||
|
|
||||||
For eventual consistency, specify the update interval as seconds:
|
|
||||||
|
|
||||||
```javascript
|
|
||||||
const db = await lancedb.connect({ uri: "./.lancedb", readConsistencyInterval: 5 });
|
|
||||||
const table = await db.openTable("my_table");
|
|
||||||

# Hybrid Search
|
|
||||||
|
|
||||||
Hybrid Search is a broad (often misused) term. It can mean anything from combining multiple methods for searching, to applying ranking methods to better sort the results. In this blog, we use the definition of "hybrid search" to mean using a combination of keyword-based and vector search.
|
|
||||||
|
|
||||||
## 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.
|
|
||||||
|
|
||||||
### Example evaluation of hybrid search with Reranking

|
||||||

||||||
Here's some evaluation numbers from experiment comparing these re-rankers on about 800 queries. It is modified version of an evaluation script from [llama-index](https://github.com/run-llama/finetune-embedding/blob/main/evaluate.ipynb) that measures hit-rate at top-k.

### Conclusion
|
|
||||||
|
|
||||||
The results show that the reranking methods are able to improve the search results. However, the improvement is not consistent across all rerankers. The choice of reranker depends on the dataset and the application. It is also important to note that the reranking methods are not a replacement for the search methods. They are complementary and should be used together to get the best results. The speed to recall tradeoff is also an important factor to consider when choosing the reranker.

# Hybrid Search
|
|
||||||
|
|
||||||
LanceDB supports both semantic and keyword-based search (also termed full-text search, or FTS). In real world applications, it is often useful to combine these two approaches to get the best best results. For example, you may want to search for a document that is semantically similar to a query document, but also contains a specific keyword. This is an example of *hybrid search*, a search algorithm that combines multiple search techniques.

You can perform hybrid search in LanceDB by combining the results of semantic and full-text search via a reranking algorithm of your choice. LanceDB provides multiple rerankers out of the box. However, you can always write a custom reranker if your use case need more sophisticated logic .
|
|
||||||
|
|
||||||
```python
|
|
||||||
import os
|
|
||||||
|
|
||||||
import lancedb
|
|
||||||
import openai
|
|
||||||
from lancedb.embeddings import get_registry
|
|
||||||
from lancedb.pydantic import LanceModel, Vector
|
|
||||||
|
|
||||||
db = lancedb.connect("~/.lancedb")
|
|
||||||
|
|
||||||
# Ingest embedding function in LanceDB table
|
|
||||||
# Configuring the environment variable OPENAI_API_KEY
|
|
||||||
if "OPENAI_API_KEY" not in os.environ:
|
|
||||||
# OR set the key here as a variable
|
|
||||||
openai.api_key = "sk-..."
|
|
||||||
embeddings = get_registry().get("openai").create()
|
|
||||||
|
|
||||||
class Documents(LanceModel):
|
|
||||||
vector: Vector(embeddings.ndims()) = embeddings.VectorField()
|
|
||||||
text: str = embeddings.SourceField()
|
|
||||||
|
|
||||||
table = db.create_table("documents", schema=Documents)
|
|
||||||
|
|
||||||
data = [
|
|
||||||
{ "text": "rebel spaceships striking from a hidden base"},
|
|
||||||
{ "text": "have won their first victory against the evil Galactic Empire"},
|
|
||||||
{ "text": "during the battle rebel spies managed to steal secret plans"},
|
|
||||||
{ "text": "to the Empire's ultimate weapon the Death Star"}
|
|
||||||
]
|
|
||||||
|
|
||||||
# ingest docs with auto-vectorization
|
|
||||||
table.add(data)
|
|
||||||
|
|
||||||
# Create a fts index before the hybrid search
|
|
||||||
table.create_fts_index("text")
|
|
||||||
# hybrid search with default re-ranker
|
|
||||||
results = table.search("flower moon", query_type="hybrid").to_pandas()
|
|
||||||
```
|
|
||||||
|
|
||||||
By default, LanceDB uses `LinearCombinationReranker(weight=0.7)` to combine and rerank the results of semantic and full-text search. You can customize the hyperparameters as needed or write your own custom reranker. Here's how you can use any of the available rerankers:
|
|
||||||
|
|
||||||
|
|
||||||
### `rerank()` arguments
|
|
||||||
* `normalize`: `str`, default `"score"`:
|
|
||||||
The method to normalize the scores. Can be "rank" or "score". If "rank", the scores are converted to ranks and then normalized. If "score", the scores are normalized directly.
|
|
||||||
* `reranker`: `Reranker`, default `LinearCombinationReranker(weight=0.7)`.
|
|
||||||
The reranker to use. If not specified, the default reranker is used.
|
|
||||||
|
|
||||||
|
|
||||||
## Available Rerankers
|
|
||||||
LanceDB provides a number of re-rankers out of the box. You can use any of these re-rankers by passing them to the `rerank()` method. Here's a list of available re-rankers:
|
|
||||||
|
|
||||||
### Linear Combination Reranker
|
|
||||||
This is the default re-ranker used by LanceDB. It combines the results of semantic and full-text search using a linear combination of the scores. The weights for the linear combination can be specified. It defaults to 0.7, i.e, 70% weight for semantic search and 30% weight for full-text search.
|
|
||||||
|
|
||||||
|
|
||||||
```python
|
|
||||||
from lancedb.rerankers import LinearCombinationReranker
|
|
||||||
|
|
||||||
reranker = LinearCombinationReranker(weight=0.3) # Use 0.3 as the weight for vector search
|
|
||||||
|
|
||||||
results = table.search("rebel", query_type="hybrid").rerank(reranker=reranker).to_pandas()
|
|
||||||
```
|
|
||||||
|
|
||||||
### Arguments
|
|
||||||
----------------
|
|
||||||
* `weight`: `float`, default `0.7`:
|
|
||||||
The weight to use for the semantic search score. The weight for the full-text search score is `1 - weights`.
|
|
||||||
* `fill`: `float`, default `1.0`:
|
|
||||||
The score to give to results that are only in one of the two result sets.This is treated as penalty, so a higher value means a lower score.
|
|
||||||
TODO: We should just hardcode this-- its pretty confusing as we invert scores to calculate final score
|
|
||||||
* `return_score` : str, default `"relevance"`
|
|
||||||
options are "relevance" or "all"
|
|
||||||
The type of score to return. If "relevance", will return only the `_relevance_score. If "all", will return all scores from the vector and FTS search along with the relevance score.
|
|
||||||
|
|
||||||
### Cohere Reranker
|
|
||||||
This re-ranker uses the [Cohere](https://cohere.ai/) API to combine the results of semantic and full-text search. You can use this re-ranker by passing `CohereReranker()` to the `rerank()` method. Note that you'll need to set the `COHERE_API_KEY` environment variable to use this re-ranker.
|
|
||||||
|
|
||||||
```python
|
|
||||||
from lancedb.rerankers import CohereReranker
|
|
||||||
|
|
||||||
reranker = CohereReranker()
|
|
||||||
|
|
||||||
results = table.search("vampire weekend", query_type="hybrid").rerank(reranker=reranker).to_pandas()
|
|
||||||
```
|
|
||||||
|
|
||||||
### Arguments
|
|
||||||
----------------
|
|
||||||
* `model_name` : str, default `"rerank-english-v2.0"`
|
|
||||||
The name of the cross encoder model to use. Available cohere models are:
|
|
||||||
- rerank-english-v2.0
|
|
||||||
- rerank-multilingual-v2.0
|
|
||||||
* `column` : str, default `"text"`
|
|
||||||
The name of the column to use as input to the cross encoder model.
|
|
||||||
* `top_n` : str, default `None`
|
|
||||||
The number of results to return. If None, will return all results.
|
|
||||||
|
|
||||||
!!! Note
|
|
||||||
Only returns `_relevance_score`. Does not support `return_score = "all"`.
|
|
||||||
|
|
||||||
### Cross Encoder Reranker
|
|
||||||
This reranker uses the [Sentence Transformers](https://www.sbert.net/) library to combine the results of semantic and full-text search. You can use it by passing `CrossEncoderReranker()` to the `rerank()` method.
|
|
||||||
|
|
||||||
```python
|
|
||||||
from lancedb.rerankers import CrossEncoderReranker
|
|
||||||
|
|
||||||
reranker = CrossEncoderReranker()
|
|
||||||
|
|
||||||
results = table.search("harmony hall", query_type="hybrid").rerank(reranker=reranker).to_pandas()
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
### Arguments
|
|
||||||
----------------
|
|
||||||
* `model` : str, default `"cross-encoder/ms-marco-TinyBERT-L-6"`
|
|
||||||
The name of the cross encoder model to use. Available cross encoder models can be found [here](https://www.sbert.net/docs/pretrained_cross-encoders.html)
|
|
||||||
* `column` : str, default `"text"`
|
|
||||||
The name of the column to use as input to the cross encoder model.
|
|
||||||
* `device` : str, default `None`
|
|
||||||
The device to use for the cross encoder model. If None, will use "cuda" if available, otherwise "cpu".
|
|
||||||
|
|
||||||
!!! Note
|
|
||||||
Only returns `_relevance_score`. Does not support `return_score = "all"`.
|
|
||||||
|
|
||||||
|
|
||||||
### ColBERT Reranker
|
|
||||||
This reranker uses the ColBERT model to combine the results of semantic and full-text search. You can use it by passing `ColbertrReranker()` to the `rerank()` method.
|
|
||||||
|
|
||||||
ColBERT reranker model calculates relevance of given docs against the query and don't take existing fts and vector search scores into account, so it currently only supports `return_score="relevance"`. By default, it looks for `text` column to rerank the results. But you can specify the column name to use as input to the cross encoder model as described below.
|
|
||||||
|
|
||||||
```python
|
|
||||||
from lancedb.rerankers import ColbertReranker
|
|
||||||
|
|
||||||
reranker = ColbertReranker()
|
|
||||||
|
|
||||||
results = table.search("harmony hall", query_type="hybrid").rerank(reranker=reranker).to_pandas()
|
|
||||||
```
|
|
||||||
|
|
||||||
### Arguments
|
|
||||||
----------------
|
|
||||||
* `model_name` : `str`, default `"colbert-ir/colbertv2.0"`
|
|
||||||
The name of the cross encoder model to use.
|
|
||||||
* `column` : `str`, default `"text"`
|
|
||||||
The name of the column to use as input to the cross encoder model.
|
|
||||||
* `return_score` : `str`, default `"relevance"`
|
|
||||||
options are `"relevance"` or `"all"`. Only `"relevance"` is supported for now.
|
|
||||||
|
|
||||||
!!! Note
|
|
||||||
Only returns `_relevance_score`. Does not support `return_score = "all"`.
|
|
||||||
|
|
||||||
### OpenAI Reranker
|
|
||||||
This reranker uses the OpenAI API to combine the results of semantic and full-text search. You can use it by passing `OpenaiReranker()` to the `rerank()` method.
|
|
||||||
|
|
||||||
!!! Note
|
|
||||||
This prompts chat model to rerank results which is not a dedicated reranker model. This should be treated as experimental.
|
|
||||||
|
|
||||||
!!! Tip
|
|
||||||
- You might run out of token limit so set the search `limits` based on your token limit.
|
|
||||||
- It is recommended to use gpt-4-turbo-preview, the default model, older models might lead to undesired behaviour
|
|
||||||
|
|
||||||
```python
|
|
||||||
from lancedb.rerankers import OpenaiReranker
|
|
||||||
|
|
||||||
reranker = OpenaiReranker()
|
|
||||||
|
|
||||||
results = table.search("harmony hall", query_type="hybrid").rerank(reranker=reranker).to_pandas()
|
|
||||||
```
|
|
||||||
|
|
||||||
### Arguments
|
|
||||||
----------------
|
|
||||||
* `model_name` : `str`, default `"gpt-4-turbo-preview"`
|
|
||||||
The name of the cross encoder model to use.
|
|
||||||
* `column` : `str`, default `"text"`
|
|
||||||
The name of the column to use as input to the cross encoder model.
|
|
||||||
* `return_score` : `str`, default `"relevance"`
|
|
||||||
options are "relevance" or "all". Only "relevance" is supported for now.
|
|
||||||
* `api_key` : `str`, default `None`
|
|
||||||
The API key to use. If None, will use the OPENAI_API_KEY environment variable.
|
|
||||||
|
|
||||||
|
|
||||||
## Building Custom Rerankers
|
|
||||||
You can build your own custom reranker by subclassing the `Reranker` class and implementing the `rerank_hybrid()` method. Here's an example of a custom reranker that combines the results of semantic and full-text search using a linear combination of the scores.
|
|
||||||
|
|
||||||
The `Reranker` base interface comes with a `merge_results()` method that can be used to combine the results of semantic and full-text search. This is a vanilla merging algorithm that simply concatenates the results and removes the duplicates without taking the scores into consideration. It only keeps the first copy of the row encountered. This works well in cases that don't require the scores of semantic and full-text search to combine the results. If you want to use the scores or want to support `return_score="all"`, you'll need to implement your own merging algorithm.
|
|
||||||
|
|
||||||
```python
|
|
||||||
|
|
||||||
from lancedb.rerankers import Reranker
|
|
||||||
import pyarrow as pa
|
|
||||||
|
|
||||||
class MyReranker(Reranker):
|
|
||||||
def __init__(self, param1, param2, ..., return_score="relevance"):
|
|
||||||
super().__init__(return_score)
|
|
||||||
self.param1 = param1
|
|
||||||
self.param2 = param2
|
|
||||||
|
|
||||||
def rerank_hybrid(self, query: str, vector_results: pa.Table, fts_results: pa.Table):
|
|
||||||
# Use the built-in merging function
|
|
||||||
combined_result = self.merge_results(vector_results, fts_results)
|
|
||||||
|
|
||||||
# Do something with the combined results
|
|
||||||
# ...
|
|
||||||
|
|
||||||
# Return the combined results
|
|
||||||
return combined_result
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
### Example of a Custom Reranker
|
|
||||||
For the sake of simplicity let's build custom reranker that just enchances the Cohere Reranker by accepting a filter query, and accept other CohereReranker params as kwags.
|
|
||||||
|
|
||||||
```python
|
|
||||||
|
|
||||||
from typing import List, Union
|
|
||||||
import pandas as pd
|
|
||||||
from lancedb.rerankers import CohereReranker
|
|
||||||
|
|
||||||
class MofidifiedCohereReranker(CohereReranker):
|
|
||||||
def __init__(self, filters: Union[str, List[str]], **kwargs):
|
|
||||||
super().__init__(**kwargs)
|
|
||||||
filters = filters if isinstance(filters, list) else [filters]
|
|
||||||
self.filters = filters
|
|
||||||
|
|
||||||
def rerank_hybrid(self, query: str, vector_results: pa.Table, fts_results: pa.Table)-> pa.Table:
|
|
||||||
combined_result = super().rerank_hybrid(query, vector_results, fts_results)
|
|
||||||
df = combined_result.to_pandas()
|
|
||||||
for filter in self.filters:
|
|
||||||
df = df.query("not text.str.contains(@filter)")
|
|
||||||
|
|
||||||
return pa.Table.from_pandas(df)
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! tip
|
|
||||||
The `vector_results` and `fts_results` are pyarrow tables. You can convert them to pandas dataframes using `to_pandas()` method and perform any operations you want. After you are done, you can convert the dataframe back to pyarrow table using `pa.Table.from_pandas()` method and return it.

▸ **createScalarIndex**(`column`, `replace`): `Promise`\<`void`\>
|
||||||
|
|

#### Parameters
|
||||||
|
|
||||||
|
| Name | Type | Description |
|
||||||
|
| :------ | :------ | :------ |
|
||||||
|
| `column` | `string` | The column to index |
|
||||||
|
| `replace` | `boolean` | If false, fail if an index already exists on the column Scalar indices, like vector indices, can be used to speed up scans. A scalar index can speed up scans that contain filter expressions on the indexed column. For example, the following scan will be faster if the column `my_col` has a scalar index: ```ts const con = await lancedb.connect('./.lancedb'); const table = await con.openTable('images'); const results = await table.where('my_col = 7').execute(); ``` Scalar indices can also speed up scans containing a vector search and a prefilter: ```ts const con = await lancedb.connect('././lancedb'); const table = await con.openTable('images'); const results = await table.search([1.0, 2.0]).where('my_col != 7').prefilter(true); ``` Scalar indices can only speed up scans for basic filters using equality, comparison, range (e.g. `my_col BETWEEN 0 AND 100`), and set membership (e.g. `my_col IN (0, 1, 2)`) Scalar indices can be used if the filter contains multiple indexed columns and the filter criteria are AND'd or OR'd together (e.g. `my_col < 0 AND other_col> 100`) Scalar indices may be used if the filter contains non-indexed columns but, depending on the structure of the filter, they may not be usable. For example, if the column `not_indexed` does not have a scalar index then the filter `my_col = 0 OR not_indexed = 1` will not be able to use any scalar index on `my_col`. |

#### Returns

`Promise`\<`void`\>

**`Examples`**
|
||||||

|

sometimes no rows (if your predicate matches nothing).
|
||||||
|
|
||||||
|
#### Parameters

**`Examples`**
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const con = await lancedb.connect("./.lancedb")
|
||||||
|
const data = [
|
||||||
|
{id: 1, vector: [1, 2]},
|
||||||
|
{id: 2, vector: [3, 4]},
|
||||||
|
{id: 3, vector: [5, 6]},
|
||||||
|
];
|
||||||
|
const tbl = await con.createTable("my_table", data)
|
||||||
|
await tbl.delete("id = 2")
|
||||||
|
await tbl.countRows() // Returns 2
|
||||||
|
```
|
||||||
|
|
||||||
|
If you have a list of values to delete, you can combine them into a
|
||||||
|
stringified list and use the `IN` operator:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const to_remove = [1, 5];
|
||||||
|
await tbl.delete(`id IN (${to_remove.join(",")})`)
|
||||||
|
await tbl.countRows() // Returns 1
|
||||||
|
```

In Python, LanceDB tables can also be queried with [DuckDB](https://duckdb.org/), an in-process SQL OLAP database. This means you can write complex SQL queries to analyze your data in LanceDB.
|
LanceDB is very well-integrated with [DuckDB](https://duckdb.org/), an in-process SQL OLAP database. This integration is done via [Arrow](https://duckdb.org/docs/guides/python/sql_on_arrow) .
|
||||||
|
|
||||||
This integration is done via [Apache Arrow](https://duckdb.org/docs/guides/python/sql_on_arrow), which provides zero-copy data sharing between LanceDB and DuckDB. DuckDB is capable of passing down column selections and basic filters to LanceDB, reducing the amount of data that needs to be scanned to perform your query. Finally, the integration allows streaming data from LanceDB tables, allowing you to aggregate tables that won't fit into memory. All of this uses the same mechanism described in DuckDB's blog post *[DuckDB quacks Arrow](https://duckdb.org/2021/12/03/duck-arrow.html)*.

To query the table, first call `to_lance` to convert the table to a "dataset", which is an object that can be queried by DuckDB. Then all you need to do is reference that dataset by the same name in your SQL query.
