title: Most simple way (URL?) to trigger SOLR commit of all pending docs?
body: <p>What's the most simple way to cause a SOLR installation to commit all pending docs?</p>
  
  <p>(There's no obvious way in the admin interface. There's a script called 'commit' mentioned on the page <a href="http://wiki.apache.org/solr/SolrOperationsTools" rel="noreferrer">http://wiki.apache.org/solr/SolrOperationsTools</a> -- but no hint where that lives. 'Commit' is clearly an option that can be added to any update POST, but I can't find any reference to a single URL that serves to only commit.)</p>
