• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((wang yang) OR (wang yanling))) OR (dong hoang))) OR (dong di)) y n chen yun zheng rong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((wang yang) OR (wang yanling))) or (dong hoang))) or (dong di)) y n chen yun zheng rong shu ;*".
