Abstract: A method and apparatus for a document filtering mechanism is provided. 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.
