• If you are trying to use Boolean operators, they must be ALL CAPS: wing yan ((((tuan hua) OR (yuan hui))) OR (yang hui)) can change may wong yue ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan ((((tuan hua) OR (yuan hui))) or (yang hui)) can change may wong yue ;*".
