A computer hardware-implemented method, system, and/or computer program product identifies a null set of synthetic event containing electronic files in a database of electronic files. A synthetic event, which is a non-executable descriptor of a set of context-related factors, is created. A context-based search of a database of electronic files is performed to identify a synthetic event containing electronic file that includes the synthetic event. In response to determining that there are no electronic files in the database of electronic files that contain the synthetic event, a set of binary data is transmitted/broadcast. The set of binary data includes a notice that there are no synthetic event electronic files in the database of electronic files.
