• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((cong juan) OR (cong sun)) rana ((yang jun) OR (yang jui)) ((cong shu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((cong juan) OR (cong sun)) rana ((yang jun) or (yang jui)) ((cong shu) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((cong juan) OR (cong sun)) rana ((yang jun) or (yang jui)) ((cong shu) or (wong siu)) ;*.
