• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chiet) OR (hoc thiet)) tach - ((thanh truong) OR (thanh thuong)) cac cong trong van tuan cau~.
• Adding a wildcard symbol may retrieve word variants: ((ho chiet) or (hoc thiet)) tach - ((thanh truong) or (thanh thuong)) cac cong trong van tuan cau*.
