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