title: duplicated id for ids query of elasticsearch
body: <p>When I tested ids query of elasticsearch as below , instead of getting 5 results , I just got 3 unique results because we have 3 same "930147044672688594". </p>
  
  <p>Is there any solution I can get 5 results even I have duplicated ids ? </p>
  
  <pre><code>{
  "query": {
          "ids": {
              "values": ["939335337147845048", "931522394912682989", "930147044672688594","930147044672688594","930147044672688594"]
          }
  }}
