Issue Summary

When using the REST API endpoint to get the users on the Confluence site, it doesn't return any value above 9998 count

Steps to Reproduce

1. Have a site that has more than 9999 users
2. Execute the below GET endpoint

   https://site.atlassian.net/wiki/rest/api/search/user?cql=type=user&start=9999&limit=100
   

Expected Results

The user/s (from the starting index of 9999) returned by the API.

Actual Results

The result after executing the endpoint:

{
    "statusCode": 500,
    "data": {
        "authorized": true,
        "valid": true,
        "errors": [],
        "successful": true
    },
    "message": "com.atlassian.confluence.api.service.exceptions.ServiceException: Exception executing cql as async search: "
}

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
