• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR lang) ((yang judy) OR (yang jin)) jiao che zhang yiqian ((wang sun) OR (gang sung)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wing or lang) ((yang judy) or (yang jin)) jiao che zhang yiqian ((wang sun) OR (gang sung)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((yang judy) or (yang jin)) jiao che zhang yiqian ((wang sun) OR (gang sung)) ;*.
