Langchain Cookbook Part 1: The VectorStore object not used in the VectorStores section

[SwamiKannan]

Thanks for the cookbook. Pretty insightful.

In the section for VectorStores (under Indexes), the embeddings of the text are created using
embeddings.embed_documents()
but the vectorstore (FAISS) class is imported but not used as:
db = FAISS.from_documents(texts, embeddings).

Maybe the section should include creation of the vectorstore and its usage
