Searching for armor is just plain tedious at the moment. There is no way to filter it so it will only search by armor type, or even only items you can use. It is even worse with gear for different professions being named almost identically across the board.
Perhaps it was a minor oversight in a rush to get everything going for release, but with more and more people hitting 80 and buying gear each day, adding a way to filter it to things only usable by your profession or even just armor type would be a very welcome change.
