• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y lang) OR (_ lang)) xa hoi. hieu ve cam ((tuc van) OR (thuc van)) hanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: te sach ((y lang) or (_ lang)) xa hoi. hieu ve cam ((tuc van) or (thuc van)) hanh vi cuu tre*.
