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