I have similar needs but for a slightly different use-case.
In my case, I am breaking up cores / indexes based on the month and year
so that I can add an alias that always points to the last few months,
but beyond that I want to simply unload the other indexes once they get
past a few months o
Thank you Simon, Erick and Shawn for your replies. Unfortunately, restarting

Shawn, once again thank you very much for the detailed reply.
Thanks,

but you have to know exactly how to create a core, and in SolrCloud
mode that's...interesting. It's much safer to bring the Solr no
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
core.properties. I couldn't find any API either so I eventually manually
recreated core.properties and restarted Solr.
Would be nice if the core.propert
