• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang han) OR (kang han)) run pain yang jin ((song ming) OR (song min)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang han) OR (kang han)) run pain yang jin ((song ming) or (song min)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang han) OR (kang han)) run pain yang jin ((song ming) or (song min)) ;*.
