• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing tan) OR (wing ian)) song lina ((kim song) OR (yun young)) minh ((cong shu) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing tan) OR (wing ian)) song lina ((kim song) or (yun young)) minh ((cong shu) or (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing tan) OR (wing ian)) song lina ((kim song) or (yun young)) minh ((cong shu) or (gong hui)) ;*.
