I perform search request by id:

POST operation-test/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "id": "aef07859-0ecb-46f5-9fa6-6633c0da00b8"
          }
        }
      ]
    }
  }
}

But response contains 2 documents with different ids:

  "took": 15,
  "timed_out": false,
  "_shards": {
    "total": 1,
    "successful": 1,
    "skipped": 0,

  },

          "currentCount": 1
        }
      }
    ]
  }
}

How is it able?
