>
> In lucene we essentially test each analysis component separately. we also
> give some
> good testing to the example Analyzers we provide that combine them.
> But we don't test various combinations that are possible: which is bad because
> it doesnt test possibilities for custom analyzers (especially since lots of
> solr users
> etc define their own).
