• If you are trying to use Boolean operators, they must be ALL CAPS: hut tinh hoc tap, nghien cuu hoan hoc ((nganh khoa) OR (danh hoa)) hoc dai hoi va gian dan~.
• Adding a wildcard symbol may retrieve word variants: hut tinh hoc tap, nghien cuu hoan hoc ((nganh khoa) or (danh hoa)) hoc dai hoi va gian dan*.
