• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach chep ve gioi bo sung minh ) OR ( thuat sach cha moi giai bay khong minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( tu sach chep ve gioi bo sung minh ) or ( thuat sach cha moi giai bay khong minh ))*.
