Power search in itunes 11?

The one problem I'm having with itunes 11 is that if power search is still there, i can't find it. I happen to like classical music and the itunes store was completely unusable for classical recordings in the early days (when you're looking for classical music, you need to be able to search by the name of the piece and the composer as well as the artist) until they added that.

But it seems to be gone now in itunes 11. Am I just not finding it, or if it's really gone, does anyone  know how to bring it back (and no, trying to do a search on all three criteria in the main search bar does not work)?
