• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu san) OR (thuy san)) ky ((nang ma) OR (tang ma)) hoi. thieu nien da duc va danh dai cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu san) or (thuy san)) ky ((nang ma) OR (tang ma)) hoi. thieu nien da duc va danh dai cua tu*".
