Subject Re: Reload an unloaded core
Date Tue, 02 May 2017 17:55:51 GMT
I ran into the exact same situation recently.  I unloaded from the browser
GUI which does not delete the data or instance dirs, but does delete  I couldn't find any API  either so I eventually manually
recreated and restarted Solr.

Would be nice if the file were to be renamed rather than
deleted and if there were a RESCAN action to scan for unloaded cores and
reload them.
