• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (dong di)) ya chua jia fang huei ((ying shu) OR (cong shu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (dong di)) ya chua jia fang huei ((ying shu) OR (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (dong di)) ya chua jia fang huei ((ying shu) OR (cong shu)) ;*.
