• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang xa hoi. lieu va cam ((((quoc ban) OR (luat bao))) OR (duc ban)) danh hai cua tre.
• Adding a wildcard symbol may retrieve word variants: tu sach y dang xa hoi. lieu va cam ((((quoc ban) or (luat bao))) or (duc ban)) danh hai cua tre*.
