Identification of null sets in a context-based electronic document search

A computer program product for identifying a null set of synthetic event containing files in a database of electronic files, the computer program product comprising:

• a non-transitory computer readable storage media;
• first program instructions to define a synthetic event, wherein the synthetic event is a non-executable descriptor of a set of context-related factors, wherein the synthetic event is an occurrence of a set of words in a single document, wherein a factor in the set of context-related factors is the occurrence of all words in the set of words, and wherein a context of the set of context-related factors is the single document containing all of the words in the set of words;
• second program instructions to perform a context-based search of a database of electronic files to identify a synthetic event containing electronic file, wherein the synthetic event containing electronic file comprises the synthetic event;
• and
• third program instructions to, in response to determining that there are no electronic files in the database of electronic files that contain the synthetic event, transmit a set of binary data to the requesting computer, wherein the set of binary data identifies the null set of synthetic event containing files in the database of electronic files;
• and wherein the first, second, and third program instructions are stored on the non-transitory computer readable storage media.

A computer system comprising:

• a central processing unit (CPU), a computer readable memory, and a non-transitory computer readable storage media;
• first program instructions to define a synthetic event, wherein the synthetic event is a non-executable descriptor of a set of context-related factors, wherein the synthetic event is an occurrence of a set of words in a single document, wherein a factor in the set of context-related factors is the occurrence of all words in the set of words, and wherein a context of the set of context-related factors is the single document containing all of the words in the set of words;
• second program instructions to perform a context-based search of a database of electronic files to identify a synthetic event containing electronic file, wherein the synthetic event containing electronic file comprises the synthetic event;
• and
• third program instructions to, in response to determining that there are no electronic files in the database of electronic files that contain the synthetic event, transmit a set of binary data to the requesting computer, wherein the set of binary data identifies the null set of synthetic event containing files in the database of electronic files;
• and wherein the first, second, and third program instructions are stored on the non-transitory computer readable storage media for execution by the CPU via the computer readable memory.
