Just a couple of "it would be nice" wishlist entries:

1. Add a feature to allow users to perform search using a text query string.  Sort of like the "where" clause of an sql statement. For example, to search for asian providers in LA that charge under $500, one would enter the following search string:
"Ethnicity='asian' and price <= 500 and city='LA'"

pros: very powerful and user will be able to store and easily
edit frequently used searches.
cons: steep learning curve and possible documentation/support headache.

2. A "My Favorite Searches" feature where user can store his favorite search parameters.  The search screen would then include a drop down menu with the list of recorded searches and when you click on a menu item, all the stored search fields are filled out.  User is then able to edit the fields for the current search or just perform the search right away.

pros: easy to use and great for doing repeated searches with minor or no change in search fields.
cons: ummm, can't think of any
