Referencing multiple pinecone namespaces.

[kdcokenny]

Hello, I am trying to reference multiple namespaces in Pinecone. Someone said in the discord that I just need to reference it as an array containing the namespaces ["namespace1","namespace2"] etc... I tried this, loading it vectorstore = Pinecone.from_existing_index(INDEX, embeddings, 'text', namespaces) where namespaces were a list and it didn't work. Have anyone else done this before with python? I know Chat with data did it, but that was with the javascript version of langchain, and it looks like he also turned it into a list. https://www.youtube.com/watch?v=Ix9WIZpArm0

hello @kdcokenny .
I think it is impossible to do with multiplenamespaces as list in langchain.
you should retrive documents in each namespaces and combine these results manually using reranking and so on.
please feel free to contact me if you have another questions.
thanks
