      Description

      Indri (http://lemurproject.org/indri.php) is an academic search engine developed by The University of Massachusetts and Carnegie Mellon University.  The major difference between Lucene and Indri is that Indri will give a document a "smoothing score" to a document that does not contain the search term, which has improved the search ranking accuracy in our experiments.  I have created an Indri patch, which adds the search code needed to implement the Indri AND logic as well as Indri's implementation of Dirichlet Smoothing.
