• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang cao hoi. hieu ve cam xuc ((((van hanh) OR (van ban))) OR (van thanh)) lai cho tre.
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang cao hoi. hieu ve cam xuc ((((van hanh) or (van ban))) or (van thanh)) lai cho tre*.
