• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (((dong bin) OR (dong sin)))) ya yu chen sharing tan cong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (((dong bin) OR (dong sin)))) ya yu chen sharing tan cong shu ;*".
