Can't get index.max_result_window for Elasticsearch 7 working

[Alexey_Pshenichnov]

For some reason I cannot set index.max_result_window from https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules.html#dynamic-index-settings

I have tried different options like
PUT /articles/_settings { "max_result_window" : 25000 }
and I can see that it was set when I run

GET /articles/_settings

but still, when I run any search like match_all I get only 10000 results back.

I'm aware about all memory complications associated with it but I have pretty small index less than 25K documents so I would like to enable it

Any suggestions what am I doing wrong?

try
PUT _all/_settings

{ "index" :

{ "max_result_window" : 25000

}

}
