• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach bai moi boi duong trong minh ) OR ( tu sach cha ve nguoi co hoang minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( thu sach bai moi boi duong trong minh ) or ( tu sach cha ve nguoi co hoang minh ))*.
