Isn't this what the slack search bar is for? I was sceptical of using it at first but I often find what I'm looking for by typing in one or two key words and restricting the search to certain channels that likely have the information.

Search can help address this issue if you know that people were discussing something you're interested in. However, it's possible (and in my experience likely) for an important topic to come up in a thread and not make its way back to the channel. In that case you may not know that it's something you need to search for.
