Is your feature request related to a problem? Please describe.
I am experimenting with RAGs for my corporation. We have many different information portals (Confluence and various policy websites and information sources, PDFS, etc...). While the information being returned is accurate, I would like to include the sources at the end of each chat.

Random example, lets say I ingest: https://en.wikipedia.org/wiki/Boat and I ask for the types of boats. And the user questioning wanted to know more about this. Having source displayed would be hugely helpful.

Describe the solution you'd like
At the end of a chat that pulled information from the RAG, it would be nice to be able to enable/disabled the sources used. This could look something like:

Sources:
Boat - Wikipedia - https://en.wikipedia.org/wiki/Boat

And the link should be clickable. If a PDF or something was uploaded, then just the name of the PDF (Not clickable).

Additionally, with llamaindex (Not sure what you guys are using). There are also two settings that can be set.
https://docs.llamaindex.ai/en/latest/module_guides/querying/node_postprocessors/

Similarity_top_k, which returns the top X results returned from the RAG. This sort of behavior is helpful since a user might have MANY different sources in different locations.
However this can also return junk, so being able to score the RAG results based on how well they matched. in llamaindex they have SimilarityPostprocessor, which allows you to specify that "I want the results to be at least 50% relevant or more".

For smaller deployments, it's not an issue, but once you scale to 1000+ docs ingested, then these sorts of tweaks become invaluable.

Describe alternatives you've considered
N/A
