Jakarta family of open-source Java products in September 2001 and became its own top-level Apache project in February 2005.
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.
The latest version of Lucene is 5.3.1 which was released on September 24th, 2015.
Features and common use
While suitable for any application that requires full text indexing and searching capability, Lucene has been widely recognized for its utility in the implementation of Internet search engines and local, single-site searching.
At the core of Lucene's logical architecture is the idea of a document containing fields of text. This flexibility allows Lucene's API to be independent of the file format. Text from PDFs, HTML, Microsoft Word, Mind Maps, and OpenDocument documents, as well as many others (except images), can all be indexed as long as their textual information can be extracted.
- Apache Nutch — provides web crawling and HTML parsing
- Apache Solr — an enterprise search server
- Elasticsearch — an enterprise search server
- Compass — the predecessor to Elasticsearch
- DocFetcher — a multiplatform desktop search application
- Lucene.NET — a port of Lucene written in C# and targeted at .NET Framework users. There are currently two variations of the software, differing in Generics support and a few bug fixes.
- Swiftype - an enterprise search startup based on Lucene
- Ferret — a search library for Ruby (programming language) inspired by Lucene. There is also a Ruby on Rails plugin called acts_as_ferret. Ferret utilizes Poshlib.
- Kinosearch — a search engine written in Perl and C and a loose port of Lucene. The Socialtext wiki software uses this search engine, and so does the MojoMojo wiki. It is also used by the Human Metabolome Database (HMDB) and the Toxin and Toxin-Target Database (T3DB).
- Apache Lucy is a successor project of both KinoSearch and Ferret, being jointly developed by the authors of these and having bindings in both Perl and Ruby.
- Luke — A Java-based GUI for Lucene which allows you to display and modify indexes.
For a list of companies that use Lucene (rather than extend), see Lucene's "Powered By" page. As an example, Twitter is using Lucene for its real time search.
