bq: Is there a way that solr can recover without losing docs in this scenario?
Not that I know of currently. SolrCloud is designed to _not_ lose documents as long as all leaders are present. And when a leader goes down, assuming there's a replica handy docs shouldn't be lost either. But taking down the leader then starting an out-of-date replica up and hoping that Solr has somehow magically cached all the intervening updates is not a supported scenario. Perhaps SOLR-5468 will help here, I'm not entirely sure. This scenario seems out-of-band though.
