Extracted from the OFBiz content component the dependencies on Lucene and created a new specialpurpose/lucene component in order to simplify the integration of components based on Lucene/Solr and to simplify the management of conflicts caused by different versions of Solr/Lucene jars.
In this way it will be easier to compare the ootb Lucene integration with custom ones (based on Lucene/Solr/etc...) and to switch between them.
