• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu ((nang xa) OR (lang xa)) hoi. hieu ((van cau) OR (phan tu)) xuc van hanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: te sach thu ((nang xa) or (lang xa)) hoi. hieu ((van cau) or (phan tu)) xuc van hanh vi cuu tre*.
