• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan wang) OR (yan guan)) ((yuan hui) OR (than china)) pei ((yang i) OR (yang yi)) long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (yan guan)) ((yuan hui) or (than china)) pei ((yang i) OR (yang yi)) long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) or (yan guan)) ((yuan hui) or (than china)) pei ((yang i) OR (yang yi)) long do ;*.
