• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu tinh)) - thanh trung cua dung ((cong manh) OR (duong manh)) van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu tinh)) - thanh trung cua dung ((cong manh) OR (duong manh)) van ban".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu tinh)) - thanh trung cua dung ((cong manh) OR (duong manh)) van ban*.
