Thanks for the suggestion But

Have you checked the nodes to see if it has relevant information, maybe you need nodes with more information

Yes, they have, it returns correct response with ListIndex, but no vectorstoreindex

I am not sure, but I think ListIndex will pass all nodes to the LLM, it will be slow and expensive

Yeah, that's the problem

I will see what I can find, thanks

You can try adjusting the top k or chunk size for a vector index.

Or if you have documents that can be split into clear categories, an index for each category/section combined with a sub question engine or a data agent is a good choice
