If I have multiple indexes to query

can you say more about why you have multiple indices?

i have two integrations - one with notion, one with gdrive.

the vectors are stored in pinecone in the format team_id-notion team_id-gdrive in the same index.

I want to query both together, but whether they exist at the same time cannot be guarenteed, one may exist without the other

sorry - those are the pinecone namespaces

Is there specific information in one vs. the other?

Maybe the best approach is summarizing each index, and using that summary in a router retriever?

no, generally the two have the same kind of information in them

hmm, I would say ideally these both get inserted into the some index, rather than different namespaces/indexes 🤔

You can insert into an existing index with index.insert(document)
