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