Abstract
In a distributed system, each of N machines receives a similarity search query through a linear communication orbit. The similarity search query includes token identifiers corresponding to tokens in a target document. Each machine, in response, identifies files that meet predefined similarity criteria with respect to the target document. Subsequent to receiving the similarity search query, the machine generates a first report, including a count of files stored at the machine that meet the predefined similarity criteria with respect to the target document, and/or information identifying a set of files that meet the predefined similarity criteria with respect to the target document; and sends the first report to a server through the linear communication orbit. The server produces a merged report presenting information with respect to files at a set of machines, including the N machines, that meet the predefined similarity criteria with respect to the target document.
