Hello, I have 1 index per day.  
I want to delete all my data that is older than 1 week, not to saturate my disk space.  
What should I do for that :

1. delete index ([Delete Index](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-delete-index.html))
2. delete all documents of my index ([Delete By Query API](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-delete-by-query.html))
3. Delete all documents of my index and then delete index
4. Delete documents, shrink, delete index

Thank you for advance.

Just delete the old indices, it's a super quick operation and the OS should be able to reclaim the space.

You could also use Curator. Set it up to delete indices, then run as a cron job. I do that, and it works a treat.

Thank you, I will see that, if it's better than launching my shell script with crontab.
