• If you are trying to use Boolean operators, they must be ALL CAPS: (( thuat sach cha me giao cong duong minh ) OR ( thu thanh va ve gioi can thong minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( thuat sach cha me giao cong duong minh ) or ( thu thanh va ve gioi can thong minh ))*.
