Moved to the proper channel:

Hello, I've been playing around with https://docs.llamaindex.ai/en/stable/examples/vector_stores/postgres/ but I can't quite seem to find a way to xref documents to overarching identifiers.

Maybe I'm not approaching it in the right way, but the current configuration is that I have multiple different high level topics with metadata associated with them, and a group of documents. I want to only use the vector_store associated with the documents tied to the higher level topic, not all possible documents.

Is this possible with llama-index?
