Abstract
A method of presenting clusters of documents in response to a search query where the documents within a cluster are determined to be related to one another. This relationship is assessed by comparing documents which match one or more terms in the query to determine the extent to which the documents have commonality with respect to terms appearing infrequently in the collection of documents. As a consequence, the cluster of documents represents a response or query result that is split across multiple documents. In a further variation the cluster can be constituted by a structured document and an unstructured document.
