Powers smart search and indexing solutions for AOL, Apple, Comcast, Disney, 
IBM, LinkedIn, Twitter, Wikipedia, and more.


Forest Hill, MD – 27 September 2011 – pThe Apache Software Foundation (ASF), 
the all-volunteer developers, stewards, and incubators of nearly 150 Open 
Source projects and initiatives, today announced the 10th anniversary of Apache 
Lucene.

The Lucene information retrieval software was first developed in 1997, entered 
the ASF as a sub-project of the Apache Jakarta project in 2001, and became a 
standalone, Top-Level Project (TLP) in 2005. Apache Top-Level Projects and 
their communities demonstrate that they are well-governed under the 
Foundation’s meritocratic, consensus-driven process and principles.

"Ten years ago, Apache provided Lucene a home where it could build a solid 
community. Today we can see the fruit of that community, both through the wide 
breadth of Lucene-based applications deployed, and through the depth of 
improvements to Lucene made in the past decade," said Doug Cutting, ASF 
Chairman and original Lucene creator.
Apache Lucene powers smart search and indexing for eCommerce, financial 
services, business intelligence, travel, social networking, libraries, 
publishing, government, and defense solutions. 

"Lucene has changed the world by opening doors that didn't exist before it 
arrived on the Open Source scene," said ASF Member and Apache Lucene Committer 
Erik Hatcher. "Lucene has massively disrupted the enterprise/proprietary search 
market, with wide adoption around the globe in every industry."

Highly performant, Apache Lucene is in use across an array of applications, 
from mobile to Internet scale, and powers enterprise-grade search solutions for 
AOL, Apple, IBM (including its artificial intelligence-driven supercomputer 
Watson), LinkedIn, Netflix, Wikipedia, Zappos, and many other global 
organizations.

"When it arrived to ASF, Lucene immediately made a huge impact --Lucene was one 
of those technologies that made a whole generation of businesses possible-- it 
was fast, easy to use, free, and had a growing community of users and 
developers. Apache Lucene can be found in an amazing number of products and 
services we all know and use, as well as in products and services we have never 
heard of," said ASF Member and Apache Lucene Committer Otis Gospodnetic. 

"While it's been six years since I joined the Lucene community, the last two 
were certainly the most exciting," said Simon Willnauer, Vice President of 
Apache Lucene. 
Current Apache Lucene sub-projects are PyLucene and Open Relevance; other 
sub-projects, including Droids, Lucene.Net, and Lucy, have spun out of the 
project and are undergoing further development in the Apache Incubator with the 
intention of becoming standalone TLPs. Solr, the high-speed Open Source 
enterprise search platform, has merged into the Lucene project itself, whilst 
former Lucene sub-projects Hadoop, Mahout, Nutch, and Tika have all 
successfully graduated as autonomous Apache Hadoop, Apache Mahout, Apache 
Nutch, and Apache Tika TLPs.

Originally written in Java, Apache Lucene is available in many programming 
languages such as Perl, C#, C++, PHP, Python, and Ruby. "Now, 10 years later, 
Apache Lucene is backed by a large community of users, contributors and 
developers with incredible energy poured into Lucene every hour of every day of 
the year," said Gospodnetic, who is also co-author of Lucene in Action, and 
founder of Sematext International.
 
"Even after 10 years, it seems this blazing community and codebase hasn't 
reached its potential yet," added Willnauer. "I'm proud to be part of this 
community and look forward to another decade of Open Source Search."

Hatcher, who is also co-author of Lucene in Action and co-founder of Lucid 
Imagination, added, "if you need search (and you do!), Lucene is the best core 
technology choice."

Hatcher, Willnauer, and other members of the Apache Lucene community will be 
presenting sessions on data handling and analytics –-a.k.a. "Lucene and 
Friends"-- including what's upcoming in Apache Lucene 4.0 (with performance 
improvements up to 20,000% from previous versions and more) at ApacheCon, 7-11 
November 2011, in Vancouver, Canada.  To register, visit http://apachecon.com/

Availability and Oversight
Apache Lucene software is released under the Apache License v2.0, and is 
overseen by a self-selected team of active contributors to the project. A 
Project Management Committee (PMC) guides the Project's day-to-day operations,
