• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach hoi dap, nghiep cao cong hoc nganh khong hoc ((ma hoi) OR (ma hoa)) dan nhan van~.
• Adding a wildcard symbol may retrieve word variants: tu sach hoi dap, nghiep cao cong hoc nganh khong hoc ((ma hoi) or (ma hoa)) dan nhan van*.
