Elasticsearch 2.1: Result window is too large (index.max_result_window)

Question

We retrieve information from Elasticsearch 2.1 and allow the user to page thru the results. When the user requests a high page number we get the following error message:

Answer 1

The right solution would be to use scrolling.
However, if you want to extend the results search returns beyond 10,000 results, you can do it easily with Kibana:

Go to Dev Tools and just post the following to your index (your_index_name), specifing what would be the new max result window

PUT your_index_name/_settings
{ 
  "max_result_window" : 500000 
}

If all goes well, you should see the following success response:

{
  "acknowledged": true
}
