first you have to define the user interface that allows to define operators other than 'is_equal'. Then you have to transfer this additional information to the search function in query.php -> q_execAttributeQuery() and create the appropriate search string modifying 'returnVar()' (where the '=' or '=~' operation is hardcoded). Because Maperver uses quite different filter definitions for shapefiles and PostGIS you have to modify this at several places.
