• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) yan tang tang ((zheng cong) OR (cheng ling)) ((hua zhong) OR (yu zhong)) siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wing) yan tang tang ((zheng cong) or (cheng ling)) ((hua zhong) or (yu zhong)) siu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wing) yan tang tang ((zheng cong) or (cheng ling)) ((hua zhong) or (yu zhong)) siu ;*.
