Discord search still sucks a lot because by nature discussions are largely unstructured. It's not really suitable for discussing specific topics - only perhaps types of topics. Discord threads could ostensibly fulfil the forum topic role, but their implementations is so utterly incompetent that it is genuinely puzzling. You can't search specific Discord threads, they often disappear from the left hand nav bar even if you subscribed to the thread. Whoever implemented the Threads in Discord should be kept away from computer systems because they are a danger to any application.

But even if Discord search was good, it still doesn't matter because it is not only a walled garden, it is a hermetically sealed chamber from which no information can escape.
