• If you are trying to use Boolean operators, they must be ALL CAPS: ((hong than) OR (long thanh)) land how co zhang ming ((tong shu) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hong than) or (long thanh)) land how co zhang ming ((tong shu) OR (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((hong than) or (long thanh)) land how co zhang ming ((tong shu) OR (wong shiu)) ;*.
