Hi,

I want to set the max scroll size explicitly through the index.max\_result\_window setting for me to experiment with the different scroll sizes. I tried to add a line (such as "index.max\_result\_window: 10000") to the elasticsearch.yml file, but once I did that I could not restart the Elasticsearch service. As long as the line is in the elasticsearch.yml file, no matter it is with a value greater than, equal to, or less than (even lot less than) 10,000 (the default), the service won't restart. However, the service restarts successfully if I comment out or remove that line.

We are on Windows Server 2012 R2.

You can't put this value in `elasticsearch.yml` but on an index level using the update indices settings API: [https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-update-settings.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-update-settings.html)
