1. A search system, comprising:
- a document interface operative to access a plurality of digitally stored documents,a topic model interface operative to access one or more digitally stored topic models,document fingerprinting logic responsive to the digitally stored topic models through the topic model interface and to the digitally stored documents through the document interface, and operative to create document fingerprints that identify topics from the digitally stored topic models in the digitally stored documents,a query interface operative to receive queries,query fingerprinting logic responsive to the digitally stored topic models through the topic model interface and to queries through the query interface, and operative to create query fingerprints that identify topics from the stored topic models in the queries, andsearch logic operative to identify one or more of the digitally stored documents that are relevant to the queries, based on the query fingerprints and the document fingerprints.

Abstract
A search system and method are disclosed. In one general aspect the method features fingerprinting digitally stored documents and queries based on one or more topic models. Similarities between document and query fingerprints can be detected to search for documents. Topic summaries can also be derived from the documents and queries based on the topic models.
