• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (dan ky)) nang xa hoi. hieu ve cam ((luc van) OR (duc van)) hanh vai cua tre.
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) or (dan ky)) nang xa hoi. hieu ve cam ((luc van) or (duc van)) hanh vai cua tre*.
