Elasticsearch delete after field time

I have an index containing data with the field "expirationDate" which is a datetime object. I want to set these documents to automatically delete after that time has passed? Is there anyway to do this, or anyway I can cron this within elasticsearch to automatically run once an hour?

You need to enable TTL for your index (see documentation) and then add _ttl field to documents containing number of milliseconds till expirationDate.

Of course, you need to remember to update _ttl field whenever expirationDate changes.

The only way (I can think of) to set the document to expire on specific time is definitely hacky. You could configure _timestamp path to point to your expirationDate field and set _ttl to 1 millisecond. It could work, but for me it sounds a little bit like a 'feature abuse'.
