• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach hoi tap, nghien cuu mot hoc ((nganh khong) OR (danh hoa)) hoc xa hai van nhan van~.
• Adding a wildcard symbol may retrieve word variants: tu sach hoi tap, nghien cuu mot hoc ((nganh khong) or (danh hoa)) hoc xa hai van nhan van*.
