lucene-skos's Issues

Looking forwad to updating to lucene 6.x

As the lucene comes to 6.3.0, it would be great to see the source updated as well.

docs/solr/schema.xml in 0.2-dev needs updates for solr 3.6.0

I just pulled 0.2-dev and integrated into a fresh Solr 3.6.0 deployment, however, I am not getting the expected query result for "arms", etc. Does /docs/solr/schema.xml need to be updated? The one in docs/solr/schema.xml looks based off version 1.2:

... the README.md probably needs these updates also. thanks, JH

To have the plugin loading as expected, I had to change SKOSFilterFactory from protected to public. Everything else seems to work fine, once constructor set as public.

Is it a bug or did I miss something? I'm using Solr 4.5.1, Tomcat 7.0.42 and OpenJDK 1.7.0_45).
