• If you are trying to use Boolean operators, they must be ALL CAPS: cao cho van - canh tranh cua thuong cong ((dan toan) OR (((van toan) OR (van tuan)))) cao~.
• Adding a wildcard symbol may retrieve word variants: cao cho van - canh tranh cua thuong cong ((dan toan) or (((van toan) or (van tuan)))) cao*.
