Requirement to fetch records beyond 10000 records

[Saurav Yadav via users]

Hi Team,

We need to fetch records beyond 10000 to be displayed on a UI dashboard.

I am using /cxs/profiles/search endpoint with the following body.

"{"offset":9990,"limit":10,"sortby":"systemProperties.lastUpdated:desc"}"

Results are coming as below which is fine (although totalSize is wrong as 
10000, around 11k profiles are there - check using count endpoint).

{
  "list": [ ... trimmed ... ],
  "offset": 9990,
  "pageSize": 10,
  "totalSize": 10000,
  "totalSizeRelation": "GREATER_THAN_OR_EQUAL_TO"

However, if call the endpoint with below body, it returns 204 with no response.

"{"offset":10000,"limit":10,"sortby":"systemProperties.lastUpdated:desc"}"

How can I fetch records more than 10k? Is there some Elasticsearch 
configuration preventing it?

Please someone let me know. Thanks in advance.
