• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sach) OR (chieu tinh)) - canh tranh va huong cong ban ((than cau) OR (than cap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) or (chieu tinh)) - canh tranh va huong cong ban ((than cau) OR (than cap))*".
