OpenSearch#
This page covers how to use the OpenSearch ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific OpenSearch wrappers.
Installation and Setup#
Install the Python package with pip install opensearch-py
Wrappers#
VectorStore#
There exists a wrapper around OpenSearch vector databases, allowing you to use it as a vectorstore
for semantic search using approximate vector search powered by lucene, nmslib and faiss engines
or using painless scripting and script scoring functions for bruteforce vector search.
To import this vectorstore:
from langchain.vectorstores import OpenSearchVectorSearch
For a more detailed walkthrough of the OpenSearch wrapper, see this notebook
