"Not" operator in iTunes search?

Just wondering if anyone knows if there is a "not" operator to exclude a word from your itunes search, say to keep if from picking upi tracks you don't want. This operator would function in a way that would be similar to the "-" operator on google, so you could search for:
apple -computer
to get all apple results that did not include the word computer. On iTunes I'd love to do things like search for:
U2 -Zooropa
and get all of U2 except Zooropa, but I don't think you can.

I realize I could make playlists to pinpoint specific sets of songs, but I don't need to save them for posterity, my preferences change so often, I just want a more refined search.
