• If you are trying to use Boolean operators, they must be ALL CAPS: (( hoc sach tham my giao con nang chinh ) OR ( tu cach mang day giai van hoang minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( hoc sach tham my giao con nang chinh ) or ( tu cach mang day giai van hoang minh ))*.
