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