If you want to get the document having the maximum value (assuming you are creating doc_id in increase numerical order from the example given) for doc_id, you can use this query:

curl "https://{es_endpoint}/sample_index/_search?pretty" -H 'Content-Type: application/json' -d'
{
  "sort" : [
    { "_id" : {"order" : "desc"}}
  ],
  "size": 1
}'
