+=item find_duplicates MODE FIELDS...
+
+Method used by _check_duplicate routines to find services with duplicate
+values in specified fields. Set MODE to 'global' to search across all
+services, or 'export' to limit to those that share one or more exports
+with this service. FIELDS is a list of field names; only services
+matching in all fields will be returned. Empty fields will be skipped.
