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