How to add a search filter for Buddypress

How to add a search filter for Buddypress based on profile information like age, sex, city or any other costum information. Yes, its for a datingsite :slight_smile: But i cant find those search/filtering functions anywhere, unless i buy a theme designed for it. But i already have a site, with a lot of other dating stuff, so i just need to implement this function.

Hope you can help

Thanks, Peter :slight_smile:
