The reply you received from Otis assumes that you're using SolrCloud. I looked back at previous messages that you have sent to the list, where you were using version 3.6, but that was over a year ago, so I don't know whether you've upgraded to 4.x yet, and I don't know if you've gone with SolrCloud. If you are not using SolrCloud, then you can do core swapping, and the next paragraph will apply. If you are using SolrCloud, then you can't; you must use collection aliasing. Do you have persistent set to true in your solr.xml? This is required for core swapping to work properly through restarts. Thanks, Shawn
