• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) yan ((((yang yun) OR (yang jun))) OR (yang yi)) zhang chen chuan zhong zhi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan ((((yang yun) OR (yang jun))) or (yang yi)) zhang chen chuan zhong zhi ;*".
