How to increase index.max_result_window on Elasticsearch?

I am using AWS lambda function to save response in S3 bucket. I am able to save response size upto 10000. But, when increased beyond 10000 I end up getting the error - Result window is too large, from + size must be less than or equal to: [10000] but was [25000]. I am unable to increase the limit of the index max result window size greater than 10000. How do I proceed with the issue?
