# 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:
|
|
```python
|
|
from langchain.vectorstores import OpenSearchVectorSearch
|
|
```
|
|
|
|
For a more detailed walkthrough of the OpenSearch wrapper, see [this notebook](/docs/modules/data_connection/vectorstores/integrations/opensearch.html)
