• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR lang) ((yan yuan) OR (fang yuan)) fei chen cheng ming ((hong shu) OR (cong shu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wing or lang) ((yan yuan) OR (fang yuan)) fei chen cheng ming ((hong shu) or (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((yan yuan) OR (fang yuan)) fei chen cheng ming ((hong shu) or (cong shu)) ;*.
