you can still do that with Solr, you can even do it as a Solr plugin (I 
would suggest a RequestHandler that you hit after each DIH call) so 
you can reuse your existing code that deals directly with an IndexReader 
-- but you'd probably want to tweak it a bit to use the UpdateHandler from 
the SolrCore instead of deleting the doc direclty, that way it's logged 
properly and you can trigger a commit to make Solr aware you've modified 
the index.
