• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang ying) OR (wang jing)) yang di li song ming ((gong hui) OR (wang hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ying) or (wang jing)) yang di li song ming ((gong hui) OR (wang hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang ying) or (wang jing)) yang di li song ming ((gong hui) OR (wang hui)) ;*.
