• If you are trying to use Boolean operators, they must be ALL CAPS: fan ying change der smart using hiring ((((doug bin) OR (dort hin))) OR (dong sin)) ;~.
• Adding a wildcard symbol may retrieve word variants: fan ying change der smart using hiring ((((doug bin) or (dort hin))) or (dong sin)) ;*.
