• If you are trying to use Boolean operators, they must be ALL CAPS: ((long thanh) OR (dong di)) nan yuan cheng ha ((sing tonga) OR (using tongue)) eiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((long thanh) or (dong di)) nan yuan cheng ha ((sing tonga) OR (using tongue)) eiu ;~".
• Adding a wildcard symbol may retrieve word variants: ((long thanh) or (dong di)) nan yuan cheng ha ((sing tonga) OR (using tongue)) eiu ;*.
