• If you are trying to use Boolean operators, they must be ALL CAPS: su sach hoc tap, nghiep cay cong hoa ((nganh khoa) OR (hang hoa)) hoc xa hoc danh nhan van~.
• Adding a wildcard symbol may retrieve word variants: su sach hoc tap, nghiep cay cong hoa ((nganh khoa) or (hang hoa)) hoc xa hoc danh nhan van*.
