You can use the same technique: 980:0->z NOT 918__c:0->z assuming your department field contains Latin-1 style of values. Or, slightly better, you can search for !->~, that would catch symbols from `!' (character 33) through digits and letters up to symbol `~' (character 126). If you use accented letters and/or other UTF-8 values, then please alter the border values accordingly. Best regards -- Tibor Simko ** CERN Document Server ** <http://cds.cern.ch/>
