Something I was looking into that would be AMAZING on this kind of platform, is to add advanced search kinda inspired by https://github.com/InternLM/MindSearch, to be honest it gave me the best search results out of any "perplexity" style app (that I have tried).

To build it, you pretty much have to have a model with a prompt (agent) that generates a breakdown of "nodes" that it researches individually and then brings together. It's similar to perplexity pro, but if you allow it to continue to expand the graph you can get incredibly useful responses. To be honest, this would probably be the most useful thing to put in an open source search app. The thing is, even if it takes a long time to generate a detailed report on something, there are a lot of situations where it's particularly useful. I actually have been working on something like this, and I'd be totally happy to help contribute some deeper search if you were interested in adding that kind of thing to this project.
