Searching User Profile Fields

[Steve Hoffmeyer]

Is there any way to do a Greater Than ">" or Less Than "<" search on a User Profile Field?

I would like to add a private User Profile Field "Expiration Date" to my forum, and be able to search this for for members who's Expiration Date has lapsed.

In other words I would like to put something like "<20090906" in the search for users section to extract users whose Expiration date is less than 9/6/2009.
