### 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")

## Improving retriever performance
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 example, we can now rerank the results using more complex rerankers.
## 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.
### Synthetic LLama2 paper dataset
| Query Type | Hit-rate@5 |
| --- | --- |
| Vector | 0.640 |
| FTS | 0.595 |
| Reranked vector | 0.677 |

| Hybrid | 0.759 |

## 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.

# 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?")
```
### 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.
