• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong tang n gain ((yang xi) OR (yang di)) ((kang han) OR (zhang han)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong tang n gain ((yang xi) or (yang di)) ((kang han) OR (zhang han)) ;*".
