# How to Integrate LangChain with MongoDB Atlas Vector Search to realise the true potential of Retrieval Augmented Generation

This Repo shows how to integrate LangChain, Open AI and store embeddings in the MongoDB Atlas and run a similarity search using MongoDB Atlas Vector Search.

## The Notebook shows how to 

- create a vector search index using the MongoDB Atlas GUI and

- how can we store vector embeddings in MongoDB documents create a vector search index using the MongoDB Atlas GUI

- perform KNN search using Approximate Nearest Neighbors algorithm which uses the Hierarchical Navigable Small World (HSNW) graphs

and also throws some light on

- Comparing textual and fuzzy search with semantic search
