Set default value to elasticsearch index.max_inner_result_window parameter

问题

I'm actually using elasticsearch 6.7 and I get an error while searching in ES :

Top hits result window is too large, the top hits aggregator [instances]'s from + size must be less than or equal to: [100] but was [2147483647]. This limit can be set by changing the [index.max_inner_result_window] index level setting.

I know how to change this parameter, this is not the issue.

I actually use this to change the parameter on existing indexes:

PUT _all/_settings
{
  "index.max_inner_result_window": "2147483647"
}

However, elasticsearch will not update future indexes that will be created.

My app often put documents in new indexes. If the index doesn't exist, elasticsearch creates it. However I don't want to run this request everytime a document is put inside an index.

The issue is when a new index is created when a document is put inside, it keep the default value to 100 for this index.

There is a paramter in es.yaml to set the default limit, however, it seems to be deprecated and not working.

What I want is that ES set automatically the limit to the integer max value when a new index is created without running the request each time I put a document in ES.

Thank you for reading, hope you can help me.

Can you try defining this in the index template like below so that all the new index created will have this setting.

{
    "index_patterns": [
        "*" // note this
    ],
    "template": {
        "settings": {
            "index":{
                "max_inner_result_window": 2147483647
            }
        }
    }
}
