This came out last week but I am still on vacation with my family in Aruba, so while I purchased internet for 1 day I thought I would share. A few months ago we came out with a new search that did everything for everyone. Unfortunately it needed to do a little more and we finally released those parts:
Browse: Now you can find that friend from class or person you saw in your geography. Yes I have no friends and removed people from results for privacy:)
Advanced Search: So you can find exactly what you are looking for.
Classmate Search: Did you want to find all your friends from high school?
