A document indexing mechanism is described. A first document is parsed into elements, and a deterministic pseudo-random score is calculated for at least some of the elements. A subset of the scores is selected based on the values of the scores. The subset of the scores is used as multiple indexes into a database of documents.
parsing at least a part of a first document into a plurality of multi-word elements, adjacent elements sharing words; calculating a deterministic pseudo-random score for each element; selecting only a small subset of the scores based on values of the scores and discarding the remaining scores; and using the small subset of the scores as multiple indexes into a database of documents, to declare a match between the first document and another document.
