• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang ((((ho hoi) OR (hoa hoi))) OR (hoc hoi)). hieu he nam thuc van hanh ve cua viet~.
• Adding a wildcard symbol may retrieve word variants: su sac ky nang ((((ho hoi) or (hoa hoi))) or (hoc hoi)). hieu he nam thuc van hanh ve cua viet*.
