• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) hyoung yan huang wang yong jui ((zhang han) OR (zhang yan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) hyoung yan huang wang yong jui ((zhang han) OR (zhang yan)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) hyoung yan huang wang yong jui ((zhang han) OR (zhang yan)) ;*.
