DOCUMENT CLASSIFICATION FILTER FOR SEARCH QUERIES

A document classifier, executed by a processing device, groups a plurality of stored documents using machine learning to create a plurality clusters that each include documents having similar characteristics. The document classifier further determines a document classification for each of the plurality of clusters based on a subset of the documents in each respective cluster. In addition, the document classifier associates a determined document classification with each of the plurality of documents, wherein resulting classifications of documents are used to filter search results in response to queries of end users.
