So I'm still a bureaucrat here, and while you don't see much of me, do I really need to step in here?
Yes, searching is hard. I am partially responsible for it being crappy if only because I'm bad at running Miraheze finance. But I did put a ton of time into organizing categories for a reason. It's not ideal for some things, but when I do Trope Workshop I always use categories to find examples -- especially if it's a genre trope.
If you don't have enough to put it in Trope Workshop, I'd suggest using the sandbox up at the top of every page, and put it in your own user space. Then you can show other people when it's ready.
Goalposts haven't moved here. I seem to remember the same goal of 5 examples over on TVT. And low example proposals were shot down quite brutally. Seen it a Million Times is not evidence it's tropable, but that you haven't quite finished resolving the pattern. If I were to move the goalposts, I'd require one category at page creation time too.
