Lucid Imagination’s certified distributions contain several software modules. They include: • Tested versions of Lucene and Solr code – which retain their Apache Software License. • Certain open source 3rd party software components (e.g., Luke) retain their current license/s. • Software developed by Lucid Imagination, but not contributed back to Apache, such as LucidGaze for Solr and Lucid’s optimized version of Kstemmer are distributed under LGPL. All free.
