• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu va cam ((xuc ban) OR (quoc ban)) hanh vai ((cua tre) OR (cua te)).
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. hieu va cam ((xuc ban) or (quoc ban)) hanh vai ((cua tre) or (cua te))*.
