How to get Value of a Specific field inside a Nested Field

[ckough (CK)]

Hi

i have created a mapping that looks like this:

PUT /mylogs_1/_mapping
{
  "properties": {
    "logEvents": {
      "type": "nested",
      "properties": {
        "id": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        },
        "message": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        },
        "timestamp:": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        }
      }
    }
  }
}

I have input a document:

PUT /mylogs_1/_doc/1
{
  "logEvents": [
      {
        "message":"abc",
        "id": "1",
        "timestamp:":"12345"
      },
      {
        "message":"def",
        "id": "2",
        "timestamp:":"10000"
      },
      {
        "message":"ggg",
        "id": "3",
        "timestamp:":"33333"
      }
  ]
}

But when I do a search:

GET /mylogs_1/_search
{
  "query": {
    "nested": {
      "path": "logEvents",
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "logEvents.message": "abc"
              }
            }
          ]
        }
      }
    }
  }
}

The return result is giving me all 3 messages inside logEvents.

{
  "took" : 2,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 1,
      "relation" : "eq"
    },
    "max_score" : 0.9808291,
    "hits" : [
      {
        "_index" : "mylogs_1",
        "_type" : "_doc",
        "_id" : "1",
        "_score" : 0.9808291,
        "_source" : {
          "logEvents" : [
            {
              "message" : "abc",
              "id" : "1",
              "timestamp:" : "12345"
            },
            {
              "message" : "def",
              "id" : "2",
              "timestamp:" : "10000"
            },
            {
              "message" : "ggg",
              "id" : "3",
              "timestamp:" : "33333"
            }
          ]
        }
      }
    ]
  }
}

How would I do the search query or the mapping such that it will only return me just

{
        "message":"abc",
        "id": "1",
        "timestamp:":"12345"
}

Thanks,
ck
