condition metadata / dyanmic conditions

Hello,

Is there a plugin / gem out there that would help me construct a dynamic set of conditions for a finder?

In other words, I have a user with multiple attributes (some 50+). I have other users that want to express preferences for befriending users based on criteria (which I'd like to store) such as specific interests, personality types, etc. (both values, ranges)

The scenario I'm confused about is how do you construct the finder for something like this

User.find(:all, :conditions => ["not sure what goes here because it'll be different for each user", current_user.preferences.attributes.collect(&:id)])

you get the idea ...

Thank you.
