Inside the results_list.php page, you will find the following line of code in several places:
CODE
if($user1!="") { $query = $query."and user1='$user1' "; }
That line is setup for exact match searching. To change it to LIKE searching, edit the line so it looks like:
CODE
if($user1!="") { $query = $query."and user1 LIKE '$user1' "; }
Now, the line can be found in many different places within the page. Basically, once for each search type. You will find it in the Zip Code search area, the City Name search area, etc... Change it in any of them if you want that type of search to be LIKE searching on the user field.
Now, ther are a total of five user fields, so you can change any or all of them to LIKE searching. You will see the same line of code for each of the user fields. User1, User2, etc...
