• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky nang xa hoi. hieu va chat luc ((((va hanh) OR (ban hanh))) OR (dia danh)) vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu san ky nang xa hoi. hieu va chat luc ((((va hanh) or (ban hanh))) or (dia danh)) vi cuu tre*.
