> I don't think so. I am not a big fan of creating delegation classes as suggested in HSEARCH-1498. I think we can expect users to migrate their Lucene API usage to Lucene 4 APIs. I would even expect that.

Maybe, I think you can easily convince me into that.. still we can remove the module in the scope of HSEARCH-1498, as I don't see how the module removal is related to Solr (especially from a user perspective)
Let's discuss it in that context ok? If I really find some easy way to make portability easier in the scope of HSEARCH-1498, we'd at least probably want to rename the module, but again that's something we can discuss after actually looking at it.
