All the indices I deal with contain logs from servers so I'd like to have Curator delete indices once the documents inside them refer to events that happened more than N days ago. Looking at the Curator documentation [https://www.elastic.co/guide/en/elasticsearch/client/curator/current/fe\_source.html#\_field\_stats\_based\_ages\_2](https://www.elastic.co/guide/en/elasticsearch/client/curator/current/fe_source.html#_field_stats_based_ages_2) it seems this is possible using `source: field_stats` however it's not clear to me what the example in documentation does and hence whether I want to use `min_value` or `max_value`

If I wanted an index to be deleted once all the documents in it refer to events more than 365 days ago, would this:

```auto
 - filtertype: age
   source: field_stats
   direction: older
   unit: days
   unit_count: 365
   field: '@timestamp'
   stats_result: max_value

```

be how to define that?

I'm using Curator 5.8. The cluster is currently running Elasticsearch 6.8 but will be upgraded to 7 in due course.
