• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong hoang) OR (wang yong)) ka hua ren ((huang tin) OR (huang lin)) ((hong ng) OR (hong jong)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong hoang) or (wang yong)) ka hua ren ((huang tin) OR (huang lin)) ((hong ng) or (hong jong)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong hoang) or (wang yong)) ka hua ren ((huang tin) OR (huang lin)) ((hong ng) or (hong jong)) ;*.
