• If you are trying to use Boolean operators, they must be ALL CAPS: (( thuat sach cha me giai cong thuong minh ) OR ( thu hoach ca ve giai chan thuong minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( thuat sach cha me giai cong thuong minh ) or ( thu hoach ca ve giai chan thuong minh ))*.
