The search is abmyssal in my opinion. I can't reliably paste links I've found elsewhere โ always have to manually change it to match the expected community syntax. I only every use it if I have to, and then I resort to search for the community of interest, and use the community view to find a post I'm looking for. Not suited for discovery in my experience.
It may have improved lately though, I wouldn't know since I'm not using it much.
