Hello folks ,  
i have this bellow JSON Data, and i want to write a Query , the Query is ,  
( **Give me all Entities where the "ai\_id" has the Value = 0** ).

the JSON Data ,

```auto
      {
        "_index": "try1",
        "_type": "_doc",
        "_id": "2",
        "_score": 1,
        "_source": {
          "target": {
            "br_id": 0,
            "an_id": 0,
            "ai_id": 0,
            "explanation": [
              "element 1",
              "element 2"
            ]
          },
          "process": {
            "an_id": 1311,
            "pa_name": "micha"
          },
          "text": "hello world"
        }
      },
      {
        "_index": "try1",
        "_type": "_doc",
        "_id": "1",
        "_score": 1,
        "_source": {
          "target": {
            "br_id": 0,
            "an_id": 1,
            "ai_id": 1,
            "explanation": [
              "element 3",
              "element 4"
            ]
          },
          "process": {
            "an_id": 1311,
            "pa_name": "luca"
          },
          "text": "the all People are good"
        }
      }
    ]
  }
}

```

I tried something like this , and did not work ,

```auto
GET try1\_search   
{
  "query":{
        { "match_all": { "ai_id": 0}}
  }
} 

```

and i tried this too , but did not work,

```auto
GET try1/_search
{
    "query": {
        "nested" : {
            "query" : {
                    "must" : [
                    { "match" : {"ai_id" : 0} }
                    ]
            }
        }
    }
}

```

Use the following query. You need to prefix `ai_id` with `target` since the field is a key of target

```auto
{
  "query": {
    "match": {
      "target.ai_id": 0
    }
  }
}

```
