• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach ((((v nang) OR (van nang))) OR (vu dang)) ma hoa. hieu ve cam vuc van anh di cua tu~.
• Adding a wildcard symbol may retrieve word variants: hoc sach ((((v nang) or (van nang))) or (vu dang)) ma hoa. hieu ve cam vuc van anh di cua tu*.
