15123:
15124: Process selected filters form course search form and pass to lonnet::courseiddump
15125: to retrieve a hash for which keys are courseIDs which match the selected filters.
15126:
15127: Inputs:
15128:
15129: dom - domain being searched
15130:
15131: type - course type ('Course' or 'Community' or '.' if any).
15132:
15133: filter - anonymous hash of criteria and their values
15134:
15135: numtitles - for institutional codes - number of categories
15136:
15137: cloneruname - optional username of new course owner
15138:
15139: clonerudom - optional domain of new course owner
15140:
15141: domcloner - Optional "domcloner" flag; has value=1 if user has ccc priv in domain being filtered by,
15142: (used when DC is using course creation form)
15143:
15144: codetitles - reference to array of titles of components in institutional codes (official courses).
15145:
15146:
15147: Returns: %courses - hash of courses satisfying search criteria, keys = course IDs, values are corresponding colon-separated escaped description, institutional code, owner and type.
