• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((wang yong) OR (wang yang)) ((hua shen) OR (hua chen)) zhang amin zhong zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((wang yong) or (wang yang)) ((hua shen) OR (hua chen)) zhang amin zhong zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((wang yong) or (wang yang)) ((hua shen) OR (hua chen)) zhang amin zhong zhi ;*.
