Available since April 2009 on SourceForge for download, OpenSearchServer was developed under the GPL v3 license and offers a series of full text lexical analyzers.
While it started as an in-house project by a private media group, OpenSearchServer is now supported by Jaeksoft, a commercial company launched in February 2010.
Version 1.1, launched in April 2009, reached the SourceForge top 15, with wide press coverage,[2][3][4] and many new users worldwide.
Since no existing search solution offered the appropriate mix of features, price and ease of use, it was decided to create new software using available open source components.
In December 2009, Keller resigned from his position with Infopro, acquired the rights to the solution and created Jaeksoft to develop services for OpenSearchServer.
