• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) or (dieu danh)) - ((nhanh tranh) OR (hanh trinh)) cua nhung cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) or (dieu danh)) - ((nhanh tranh) OR (hanh trinh)) cua nhung cong tan toan tap*.
