Confining LLaMA 2's context for RAG QA (alien.top)

So I want to ask for advice on 2 related topics:

  1. If I have a corpus of many documents embedded in a vector store, how can I dynamically select (by metadata, for example) a subset of them and only perform retrieval on that subset for answer generation.

  2. I want LLaMa to be able to say I DO NOT KNOW if the context it retrieved cannot answer the question. This behavior is not stable yet from what I have seen.

Thank you so much!

Use something like lmql, guidance or guiderails to get the model to say it doesn't know. I've also had some success with the airoboros fine-tuned models, which have this behaviour defined in the dataset using a specific prompt.
