We support two vector databases to store and search embeddings -- FAISS and Elasticsearch. Here's a code snippet showing how to use FAISS to store embeddings and search for text similar to a query. Both database backends are featured in this [example notebook] (https://github.com/hwchase17/langchain/blob/master/notebooks/examples/embeddings.ipynb).
