There sort of is, it's just very well hidden, so no one would find it unless they did a little detective work. Run a search for any word, like "page", then find the "Advanced" link and click on that, then put a check mark in the "Board Thread" check box, and it will only filter forum topics. There should be an easier way to do it though.
