• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong yang) OR (dong hoang))) OR (wang yan)) yet ma pei ((yun hui) OR (chun hui)) ping shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong yang) or (dong hoang))) or (wang yan)) yet ma pei ((yun hui) OR (chun hui)) ping shu ;*".
