After some time of using our message boards, I have realized that when you are searching for something it isn't very clear what scope you are in. I have made some changes (http://issues.liferay.com/browse/LPS-2501) that will help clear up the ambiguity a little bit.
This is how searching looks now:
Notice the search button text, how it is now clear if you are searching in a specific category, or all categories. I hope the community likes it!
