• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y nang xa hoi. hieu tu cham ((((xuc van) OR (quoc ban))) OR (duc tan)) hanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: vu sach y nang xa hoi. hieu tu cham ((((xuc van) or (quoc ban))) or (duc tan)) hanh vi cuu tre*.
