Too bad Discord can't be searched. There's lots of information trapped on Discord.

That’s a huuuge loss in my opinion, I really wish the contents of public Discord servers was indexable.

Remember a project that where supposed to fix that but I don’t know what happened, I guess no one was interested in it?

There are: AnswerOverflow (https://www.answeroverflow.com) and Linen (https://www.linen.dev).
