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