Its a huge pain in the behind now, totally aware of it, was struggling with this myself on the underrated / overrated movie topic.
We plan to change it so search automatically scopes on topic (broadening to everything if nothing found in topic) and displays multiple hits per topic.
So you would see something like this in the search results allowing you to navigate to the post.
