The corresponding query nearly returns 3 million documents.

From : 1, size : 50 =\> Response comes within 2 seconds.  
From : 1,000,000, size : 50 =\> Response comes after 20 seconds.

If we send multiple concurrent requests for the second instance, Elasticsearch instance hangs up. What are the possible approaches we can take in this scenario?

Thanks
