• If you are trying to use Boolean operators, they must be ALL CAPS: tu hanh noi tap, nghien cac ((cong hoa) OR (thanh hoa)) nganh khong hoc ma hoi van nhan va~.
• Adding a wildcard symbol may retrieve word variants: tu hanh noi tap, nghien cac ((cong hoa) or (thanh hoa)) nganh khong hoc ma hoi van nhan va*.
