• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - hanh mang va ((nhung cong) OR (dung cong)) van khanh cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - hanh mang va ((nhung cong) or (dung cong)) van khanh cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - hanh mang va ((nhung cong) or (dung cong)) van khanh cau*.
