[jira] [Created] (LUCENE-9537) Add Indri Search Engine Functionality to Lucene

Cameron VandenBerg created LUCENE-9537:
------------------------------------------

             Summary: Add Indri Search Engine Functionality to Lucene
                 Key: LUCENE-9537
                 URL: https://issues.apache.org/jira/browse/LUCENE-9537
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/search
            Reporter: Cameron VandenBerg
         Attachments: LUCENE-INDRI.patch

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.
