+         Allows you to specify an arbitrary PQF query language substring. The provided
+         string is prefixed the user's query after it has been normalized to PQF
+         internally in pazpar2. This allows you to attach complex 'filters' to
+         queries for a gien target, sometimes necessary to select sub-catalogs
+         in union catalog systems, etc.
