• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong hoang) OR (((dong sink) OR (dong sin)))) ya hua wang ((yang jin) OR (ying jin)) song shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong hoang) or (((dong sink) or (dong sin)))) ya hua wang ((yang jin) OR (ying jin)) song shin ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong hoang) or (((dong sink) or (dong sin)))) ya hua wang ((yang jin) OR (ying jin)) song shin ;*.
