Mget fails

[living_jordi]

I've tried to use _mget api using http straightforwardly:

curl -u elastic:changeme -XGET localhost:9200/index/_mget?pretty -d '
{
  "docs": [
    {
      "_type": "coll",
      "_id": "1474c1a0-2540-11e7-9271-0242ac110008"
    }
  ]
}
'

and I'm getting a not exists response:

{
  "docs" : [
    {
      "_index" : "index",
      "_type" : "coll",
      "_id" : "1474c1a0-2540-11e7-9271-0242ac110008",
      "found" : false
    }
  ]
}

However, I've tried to get this document using get api:

curl -u elastic:changeme -XGET localhost:9200/index/coll/1474c1a0-2540-11e7-9271-0242ac110008?pretty

and the response I'm getting is right:

{
  "_index" : "index",
  "_type" : "coll",
  "_id" : "1474c1a0-2540-11e7-9271-0242ac110008",
  "_version" : 1,
  "_routing" : "user",
  "found" : true,
  "_source" : {
    "user" : "user",
    "timestamp" : "2017-04-18T22:00:00Z",
    "startTimestamp" : "2017-04-18T22:00:00Z",
    "dueTimestamp" : null,
    "closingTimestamp" : null,
    "matter" : "Activity 16",
    "comment" : null,
    "status" : 20,
    "backlogStatus" : 20,
    "metainfos" : {
      "fbcbeacfbcbeacfbcbeacfbcbeacfbcbaeac" : [
        "Project A"
      ],
      "fceceacfcedeacfceeeacfcefeacfcfeac" : [
        "Example activity"
      ],
      "ffceacffceacffceacffceacffceac" : [
        "Marketing"
      ],
      "efeacefeacefeacefeacefeac" : [
        "2017-Q3"
      ],
      "ddfceacddfceacddfceacddfceacddfceac" : [
        "West"
      ],
      "eaaeaceabeaceaceaceadeaceaeeac" : [
        "2-Important - Not urgent"
      ],
      "eaceeaceaceeaceaceaeaceacebeaceaceceac" : [
        "4-Completed"
      ],
      "efeeeacefefeaceffeaceffeaceffeac" : [
        "Oliver"
      ]
    },
    "resources" : [ ],
    "notes" : null
  }
}

Any ideas?

Are you able to repreduce this behaviour consistently? I just tried locally and it worked fine for me:

PUT test/coll/1474c1a0-2540-11e7-9271-0242ac110008
{}

GET test/coll/1474c1a0-2540-11e7-9271-0242ac110008

GET test/_mget
{
  "docs": [
    {
      "_type": "coll",
      "_id": "1474c1a0-2540-11e7-9271-0242ac110008"
    }
  ]
}

What version of Elasticsearch are you using?

I'm using 5.2 version.
