member search results

I am using Elgg 1.7 and the profile_manager plugin.  Right now when I do a search of members, The users name, icon, and location are returned.  Location is one of the fields I defined using profile manager.  I'm wondering 2 things...

1.  Why does the lcoation field value get returned in the search results?

2.  How do I get the values of any other fields returned?

I'm fairly new to Elgg and am just learning how everything is put together behind the scenes so any tips on what to look for and where to look would be greatly appreciated.
