Apache Lucene
Apache Lucene is a free and open-source search engine software library, originally written in Java by Doug Cutting. It is supported by the Apache Software Foundation and is released under the Apache Software License. Lucene is widely used as a standard foundation for production search applications.
Lucene has been ported to other programming languages including Object Pascal, Perl, C#, C++, Python, Ruby and PHP.
Doug Cutting originally wrote Lucene in 1999. Lucene was his fifth search engine. He had previously written two while at Xerox PARC, one at Apple, and a fourth at Excite. It was initially available for download from its home at the SourceForge web site. It joined the Apache Software Foundation's Jakarta family of open-source Java products in September 2001 and became its own top-level Apache project in February 2005. The name Lucene is Doug Cutting's wife's middle name and her maternal grandmother's first name.
Lucene formerly included a number of sub-projects, such as Lucene.NET, Mahout, Tika and Nutch. These three are now independent top-level projects.
In March 2010, the Apache Solr search server joined as a Lucene sub-project, merging the developer communities.
Version 4.0 was released on October 12, 2012.
In March 2021, Lucene changed its logo, and Apache Solr became a top level Apache project again, independent from Lucene.
While suitable for any application that requires full text indexing and searching capability, Lucene is recognized for its utility in the implementation of Internet search engines and local, single-site searching.
