I'm actually a moderator on a discord. We have a lot of FAQ pages (generally wiki pages on various GitHub repos) that a discord bot will send you to in response to various different commands. Occasionally I use search to find a chat that I personally had with someone X months ago, and it usually works if I can find the right search terms. I don't think it is any worse than IRC with chatlogs (arguably might be better depending on how well indexed the chatlogs are). And the fundamental problem is that social chats are noisy, and you should never be using them for knowledge retention. And web forums aren't a replacement for social chat. And 99% of the questions and answers in there are from newbies and are covered in FAQs and are just noise anyway. You can't index your way out of a horrible noise problem. They also do serve a purpose because as one of the subject-matter experts (who is a single-point-of-failure/final-escalation level), I don't have to get involved in most of the discussion. There's usually dozens of people on the server who can answer the easy questions, and I can monitor for people hitting real bugs that actually need fixing.
