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