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