The way I was doing it was having an app actually scanning relays and searching for relevant content.

Can you technically describe what you did?
I vibe coded it, basically using a grok ai API to analyze notes and search and generate keywords based on the users query, then it processed the notes with ai to provide a reply.
I used Nostr tools integration for the Nostr stuff, it kinda worked but not great, sorta gave up on that project.
