Hi,

I was checking on Lucene Faceted search and need some guidance.
http://lucene.apache.org/core/4_3_0/facet/org/apache/lucene/facet/doc-files/userguide.html#facet_indexingmentions
about

    DocumentBuilder categoryDocBuilder = new CategoryDocumentBuilder(taxo);

But I am unable to find DocumentBuilder and CategoryDocumentBuilder classes
in lucene-facet-4.3.0.jar. Most of the online tutorials that I could find
also mentions the same steps as in official doc
These are present in an old version -
http://lucene.apache.org/core/old_versioned_docs/versions/3_4_0/api/contrib-facet/org/apache/lucene/DocumentBuilder.html

What are the equivalent ones in 4.3? Or any help in getting this
implemented in 4.3?

Thanks,
Rajesh
