• If you are trying to use Boolean operators, they must be ALL CAPS: (( thuat sach cham dien giao con hong minh ) OR ( thu hoach ha de gia cong trong tin ))~.
• Adding a wildcard symbol may retrieve word variants: (( thuat sach cham dien giao con hong minh ) or ( thu hoach ha de gia cong trong tin ))*.
