• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yao) OR (gang yao)) yang xi china chang ((lai chung) OR (kai hong)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yao) OR (gang yao)) yang xi china chang ((lai chung) or (kai hong)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yao) OR (gang yao)) yang xi china chang ((lai chung) or (kai hong)) shu ;*.
