• If you are trying to use Boolean operators, they must be ALL CAPS: klange ((des klage) OR (des plages)) der smart mappings usinddg ((dong di) OR (dong ping)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "klange ((des klage) OR (des plages)) der smart mappings usinddg ((dong di) or (dong ping)) ;*".
