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