• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach nghiep viet gioi he thong minh ) OR ( tu cach cha ve giai he thong minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( su sach nghiep viet gioi he thong minh ) or ( tu cach cha ve giai he thong minh ))*.
