• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang dewan ((huan tao) OR (hua xiao)) yang tin ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang dewan ((huan tao) or (hua xiao)) yang tin ((hong hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang dewan ((huan tao) or (hua xiao)) yang tin ((hong hai) OR (shang hai)) ;*.
