• If you are trying to use Boolean operators, they must be ALL CAPS: su cac ky sang tao hoi. ((hieu le) OR (hieu ve)) nam thuc ((van hanh) OR (ca dan)) di cua viet~.
• Adding a wildcard symbol may retrieve word variants: su cac ky sang tao hoi. ((hieu le) or (hieu ve)) nam thuc ((van hanh) or (ca dan)) di cua viet*.
