Datafari

Datafari is an Open source enterprise search software using Apache Solr (the projects from the Apache Software Foundation). It is a packaged search engine in a sense that it proposes the connection to data sources, the indexing, the search and the graphical administration of the system. The software is distributed (architecture of type Distributed computing) using SolrCloud. Datafari uses Apache Solr for the index and search phases. It combines Apache ManifoldCF, Apache Solr and Apache Cassandra. based on HTML5, CSS3 and jQuery.
Background
Datafari was created by France Labs. France Labs looked for an open source search software to enhance its R&D with a new intranet relevancy algorithm. The team found that there was nothing being well maintained and available under an Apache License and created Datafari. It became independent from the research on the algorithm, considering that it had search value by itself. The first open source version was released on March 4, 2015 with version number 1.0. In May 2015, thanks to Datafari, France Labs won the Big Data trophy at the IT Innovation Forum. Version 2.0 (this major version change was due to the technical migration from Solr 4 to Solr 5) has been released on Sept. 7th 2015.
The company France Labs was created end of 2011 by Cédric Ulmer, Olivier Tavard and Aurélien Mazoyer ; its headquarters are located in Nice, France.
