Update chat_with_documents.py #17

Closed bhadreshpsavani closed 10 months ago

Ideally fetch_k should be bigger than k parameter, since first it will fetch the fetch_k documents,

It will then select k document based on the search type.

Please correct me if i am wrong.

i got to know that from issue and langchain-chat-with-your-data-project -from-deeplearning.ai

@bhadreshpsavani Thanks you very much for the correction. You are absolutely right. This is explained in the vectorstores module.
