It seems that you have two sets (in the mathematical sense) and all
you want to know is if their intersection is non-empty. Easiest
solution: create two NSSet objects and use Apple's optimized
implementation of set intersection:
BOOL tagAppearsInPhrase = [tagSet intersectsSet: phraseSet];
Anything you do otherwise will likely not be as fast.
