-------------------------------------------
Summary: Add Additional Indri Search Engine Functionality to Lucene
Key: LUCENE-10157
URL: https://issues.apache.org/jira/browse/LUCENE-10157
Project: Lucene - Core
Issue Type: New Feature
Components: core/queryparser, core/search
Reporter: Cameron VandenBerg
In Jira issue LUCENE-9537, basic functionality from the Indri search engine
([http://lemurproject.org/indri.php]) was added to Lucene. With that
functionality in place, we would love to build upon that to add additional
Indri queries and an Indri query parser to Lucene to broaden the Indri
functionality within Lucene. In this patch, I have added the Indri NOT, the
INDRI OR, and the Indri WeightedSum functionality. I have also included an
IndriQueryParser for accessing this functionality. More information on these
query operators can be seen here:
[https://sourceforge.net/p/lemur/wiki/Belief%20Operations/] and here:
[https://sourceforge.net/p/lemur/wiki/Indri%20Query%20Language%20Reference/.|https://sourceforge.net/p/lemur/wiki/Indri%20Query%20Language%20Reference/]
I would be very excited to work with the Lucene community again to try to add
this functionality. I am open to suggestions, and I am happy to make any
changes that might be suggested. Thank you!
