• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky tang van hoe. hieu ve cam ((((dua ban) OR (cua ban))) OR (dia ban)) thanh hai cua tre.
• Adding a wildcard symbol may retrieve word variants: su xac ky tang van hoe. hieu ve cam ((((dua ban) or (cua ban))) or (dia ban)) thanh hai cua tre*.
