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