**Query**

```auto
"query": {
    "nested": {
      "path": "mortgagesObj",
      "query": {
        "bool": {
          "must": [
            {
              "range": {
                "mortgagesObj.regDate": {
                  "gte": "01/01/2020",
                  "lte": "24/08/2020",
                  "format": "dd/MM/yyyy||yyyy"
                }
              }
            }
          ]
        }
      }
    }
  }

```

**Question**  
Question 1 : I want to select field only between '01/01/2020' and '24/08/2020', but I am getting all the fields inside that array which I do not want.

Question 2 : Is it possible to count number of fields inside an array when I getting the output?
