• If you are trying to use Boolean operators, they must be ALL CAPS: (( so sach cha vien gioi cong dung thinh ) OR ( su sach cha le nguoi muong khong minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( so sach cha vien gioi cong dung thinh ) or ( su sach cha le nguoi muong khong minh ))*.
