• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((van nang) OR (van quang)) ma hoi. hieu ve cam ((xuc van) OR (luu van)) hanh vi su triet.
• Adding a wildcard symbol may retrieve word variants: su sach ((van nang) or (van quang)) ma hoi. hieu ve cam ((xuc van) or (luu van)) hanh vi su triet*.
