• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (daun yang)) yuan hui jin ((ying yang) OR (ying chang)) long 2 ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (daun yang)) yuan hui jin ((ying yang) OR (ying chang)) long 2 ;".
