• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - hanh mang va thong duong ((van toan) OR (van tan)) ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu sach)) - hanh mang va thong duong ((van toan) OR (van tan)) ban".
