Hi I'm learning how to maintain clean my ES and I found this article today [http://www.elastic.co/guide/en/elasticsearch/client/curator/current/examples.html](http://www.elastic.co/guide/en/elasticsearch/client/curator/current/examples.html) The first example is "Delete all indices older than". I've installed curator tool to execute the command: _# curator delete indices --older-than 14 --time-unit days --timestring '%Y.%m.%d'_ 2015-05-04 11:50:49,600 INFO Job starting: delete indices 2015-05-04 11:50:49,613 INFO Pruning Kibana-related indices to prevent accidental deletion. 2015-05-04 11:50:50,046 INFO Job completed successfully. then I've checked again my index and the index called "logstash-2015.04.19" have disappeared. So, turns out it really remove all index and the documents but then... What is difference with "close indices"?

Close leaves them on disk but removes them from being queried, which also means it takes barely any heap to maintain. It might be useful if you have lots of disk space but not much heap, it just means you have to manually open them when you want to query them.
