• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang dan) OR (wang yidan)) wang ((((hua chen) OR (yu chen))) OR (jui chen)) yang jici wang yue ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) or (wang yidan)) wang ((((hua chen) OR (yu chen))) or (jui chen)) yang jici wang yue ;".
• Adding a wildcard symbol may retrieve word variants: ((wang dan) or (wang yidan)) wang ((((hua chen) OR (yu chen))) or (jui chen)) yang jici wang yue ;*.
