• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang dan) OR (wang yidan)) wang ((hua chen) OR (jui chen)) yang jin ying yue ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) OR (wang yidan)) wang ((hua chen) or (jui chen)) yang jin ying yue ;".
