   Process selected filters form course search form and pass to lonnet::courseiddump
   to retrieve a hash for which keys are courseIDs which match the selected filters.
   
   Inputs:
   
   dom - domain being searched 
   
   type - course type ('Course' or 'Community' or '.' if any).
   
   filter - anonymous hash of criteria and their values
   
   numtitles - for institutional codes - number of categories
   
   cloneruname - optional username of new course owner
   
   clonerudom - optional domain of new course owner
   
   domcloner - Optional "domcloner" flag; has value=1 if user has ccc priv in domain being filtered by, 
               (used when DC is using course creation form)
   
   codetitles - reference to array of titles of components in institutional codes (official courses).
   
   
   Returns: %courses - hash of courses satisfying search criteria, keys = course IDs, values are corresponding colon-separated escaped description, institutional code, owner and type.
