• Performing a fuzzy search may retrieve terms with similar spellings: theo ((tieu xanh) OR (chieu xanh)) - ((hang luan) or (khang luan)) van tong cong manh toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu xanh) OR (chieu xanh)) - ((hang luan) OR (khang luan)) van tong cong manh toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) OR (chieu xanh)) - ((hang luan) or (khang luan)) van tong cong manh toan cao*".
