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