• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - hanh tranh su dung chung dan ((than cap) OR (phan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - hanh tranh su dung chung dan ((than cap) or (phan tap))*".
