• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wing tan) OR (liang tan))) OR (cong sun)) colin xu yuan wang ((tan gong) OR (tan yong)) min ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wing tan) OR (liang tan))) or (cong sun)) colin xu yuan wang ((tan gong) or (tan yong)) min ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wing tan) OR (liang tan))) or (cong sun)) colin xu yuan wang ((tan gong) or (tan yong)) min ;*.
