Discord search is horrendous. The chat and threads are nice, but finding previous messages can be difficult. I feel like there's a opportunity here for someone to make a similar platform with far better search.
It's the lack of verbatim search. I can't plonk an error message in quotes and have Discord return only comments with that. Instead I'm inundated with irrelevant comments.
This wouldn't be a problem if so many things didn't use Discord for support. It's being overloaded as a knowledge base, support forum, and community when it doesn't handle any of these functions well.
