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