Response from Solr: Generally speaking, SolrJ has been very compatible communicating to many backend Solr server versions. I wish we tracked problems about this specifically somewhere, but I don't think we do. I suggest simply using the latest SolrJ release. If you find issues, report them. Again, assuming SolrJ, it's good to have some flexibility on which SolrClient subclass is used. There's Cloud vs not (i.e. standalone), there's newer HTTP2 vs not. There's Cloud talking directly to ZooKeeper for cluster state, or there's via Solr HTTP.
