• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (hieu lang)) - canh tranh cua dung cong san ((phan cau) OR (phan tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) OR (hieu lang)) - canh tranh cua dung cong san ((phan cau) or (phan tu))*".
