• If you are trying to use Boolean operators, they must be ALL CAPS: ((moi dieu) OR (mai dien)) lang - thanh trung cam nhung ((huong van) OR (duong van)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((moi dieu) OR (mai dien)) lang - thanh trung cam nhung ((huong van) or (duong van)) toan cao".
• Adding a wildcard symbol may retrieve word variants: ((moi dieu) OR (mai dien)) lang - thanh trung cam nhung ((huong van) or (duong van)) toan cao*.
