Hi,

I want to update the refresh interval for all my existing indices(approx 200-300 indices) to 60s.  
Though I know we can achieve it using template, but per my understanding that template will be effective only for new indices.  
Is there any possible way to update refresh interval for all **existing** indices. Either on cluster basis or some other way of doing that.

You can specify **\_all** which will then affect all your indices. For instance, this will set the refresh interval to 20 seconds in all the indices:

```
curl -XPUT "http://localhost:9200/_all/_settings?pretty" -H "Content-Type: application/json" -d '{
      "index" : {
           "refresh_interval" : "20s"
      }
}'

```

That's work fine. Thanks for contributing. 👍
