• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang fan) OR (wang yan)) ying ((yue wang) OR (((yu fang) OR (yu wang)))) yang jae song jin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang fan) or (wang yan)) ying ((yue wang) or (((yu fang) OR (yu wang)))) yang jae song jin ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang fan) or (wang yan)) ying ((yue wang) or (((yu fang) OR (yu wang)))) yang jae song jin ;*.
