The Apache Lucene project develops open-source search software.


TLP

No new PMC members were added in the last quarter.  The most recent PMC
member addition happened in April 2013.

We added two new committers in the last quarter: Joel Bernstein, Ryan Ernst.
Wolfgang Hoschek rejoined the committer team after longer abstinence, leaving
the emeritus status.


Lucene Core and Solr
--------------------

Lucene Core is a search-engine toolkit.

Solr is a search server built on top of Lucene Core.

In the last quarter we made three releases of both Lucene Core and Solr:

 - 4.5.0 on 5 October 2013
 - 4.5.1 on 24 October 2013
 - 4.6.0 on 24 November 2013

The corresponding Apache Solr Reference Guides were released
as PDF versions, generated from the Confluence Wiki:

 - 4.5 on 5 October 2013
 - 4.6 on 2 December 2013

The community is very active.

The Lucene PMC was contacted by the Oracle Quality Assurance team to help
with testing EA builds of OpenJDK 8 with Lucene/Solr. Three members of the
PMC had phone conferences with Oracle's QA team, discussing about working
together in discovering bugs before releasing Java 8, to prevent serious data
corruption issues, like happened with Java 7GA in July 2011 and Java 7u40
in September 2013.

Security: There were 3 CVEs created by the Redhat security team
against version 3.6.2 of Apache Solr:

 - CVE-2013-6397
 - CVE-2013-6407
 - CVE-2013-6408

Those issues were only fixed and released in Solr 4.1 and 4.6, because no new
3.x release was planned (EOL of 3.x). The committers helped to backport the
fixes (see SOLR-5520). The PMC has not yet decided if there will be a
maintenance release of Apache Lucene/Solr 3.6.3 containing these fixes.


Open Relevance Project
----------------------

The Open Relevance Project is a project aimed at providing Lucene and others
tools for judging the quality of search and machine learning approaches.  The
community is not very active, but we don't expect it to be very high volume
either as it is a niche area.


PyLucene
--------

PyLucene is a Python integration of Lucene Java.  Development is almost
entirely an automated port, so this project will never require a lot of
developers.  The user community is active.

In the last quarter we made one release of PyLucene:

 - 4.5.1-1 on 5 November 2013
