Oh, so nce, most of the stuff I wanted are acually there =D. Thanks for the tips,

Well, I insist with the search patterns however, the use of regular expressions would aliviate the need of a the "But does not contain" field

"car"   =  Toon Car, Car and Driver, Car

car = cartoon, scarf, tooncar

car "-tooncar, scarf" = cartoon

I just point it out since is the way most search engines work, but not something I'd die for, there could be implementation problems I'm overlooking, or it could be less user friendly.

And I feel the need to congratulate and thank you again, you did a great job with this tool, for a first version its pretty much complete, few programs nail it on its initial release =)
