• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yuan hu ((yong phang) OR (hong sheng)) hai ((phong sheng) OR (hong cheng)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yuan hu ((yong phang) or (hong sheng)) hai ((phong sheng) OR (hong cheng)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yuan hu ((yong phang) or (hong sheng)) hai ((phong sheng) OR (hong cheng)) ;*.
