 - ELASTICCLOUD_USERNAME: The elastic cloud username for basic authentication. Provide this only if your elasticsearch instance is hosted on elastic cloud
 - ELASTICCLOUD_PASSWORD: The elastic cloud password for basic authentication. Provide this only if your elasticsearch instance is hosted on elastic cloud
+- MAX_RESULT_SIZE: The Results Per Query Limits. Default is `1000` (Used by the db to es migration script)
+- MAX_BULK_SIZE: The Bulk Indexing Maximum Limits. Default is `100` (Used by the db to es migration script)
 
 For `ES.DOCUMENTS` configuration, you will find multiple other configurations below it. Each has default values that you can override using the environment variables
