First, are you absolutely sure you're committing before shutting down?
Hard commit in this case, openSearcher shouldn't matter.

SolrCloud? And if not SolrCloud, how are you shutting Solr down? "Kill
-9" is evil.

If you have transaction logs enabled then you shouldn't be losing
docs, any uncommitted docs should be replayed from the transaction

This should absolutely _not_ be happening assuming hard commits
happen. One possible explanation is that you have hard commits turned
off and are using soft commits _and_ the transaction log isn't
enabled. And you kill Solr with evil intent. But that's a long chain
of "ifs"....
