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