[Feedback] Search With Selected Category Broken?

I was going to make a feedback post on some thought I had with the search feature and I notice it seems to be broken.

As a test, I just searched "Master Yi" from the search box in the community beta home. It pulled up a bunch of posts involving master yi and gave options on the right to filter by category or date range or require red posts. I selected the "Gameplay and Strategy" category and applied the filter and it gave no results. But there were clearly many Master Yi posts in gameplay and strategy.

Is something broken here?
