Project description
LlamaIndex Retrievers Integration: DuckDBRetriever
pip install llama-index-retrievers-duckdb-retriever.
What is this?
This is a BM25 Retriever for DuckDB that can be used with LlamaIndex to enable full-text search.
How to use
This was created with reference to DuckDB Full-Text Search Extension, so it's mostly the same.
Please refer to that.
However, while DuckDBVectorStore is an VectorStore, DuckDBRetriever is a Retriever.
DuckDBRetriever Example:
from llama_index.retrievers.duckdb_retriever import DuckDBRetriever
retriever = DuckDBRetriever(database_name="vector.db", persist_dir="duckdb")
nodes = retriever.retrieve("retrieve_query")
