• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan pong ((((yu cheng) OR (yu chen))) OR (jui chen)) ping guo ((wong yue) OR (wang hua)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan pong ((((yu cheng) OR (yu chen))) or (jui chen)) ping guo ((wong yue) or (wang hua)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan pong ((((yu cheng) OR (yu chen))) or (jui chen)) ping guo ((wong yue) or (wang hua)) ;*.
