Origin of Apache Solr

In late 2004, CNET Networks starts an in-house search platform project named as “Solar” (with an A).

In January 2006, CNET Networks decided to openly publish the source code by donating it to the Apache Software Foundation under the Lucene top-level project named as “Solr”.

On January 17, 2007 Solr graduated from the Apache Incubator to become a Lucene sub-project.

In March 2010, The Solr and Lucene-java sub-projects merged into a single project.

In 2011, Solr version number scheme was changed in order to match that of Lucene. After Solr 1.4.1, the next release of Solr was labeled 3.1, in order to keep Solr and Lucene on the same version number.

In October 2012 Solr version 4.0 was released, including the new Solr cloud feature.

Current Solr version relies is 4.7.2 & it is launched on 15 April 2014.
