How to match all item in nested array

[Kit_Tsang]

The mapping:

 "working_hour": {
          "type": "nested",
          "properties": {
            "from": {
              "type": "long"
            }
          }
        }

Data example:

Record 1:

   "_source" : {
          "working_hour" : [
            {
              "from" : 3
            },
            {
              "from" : 6
            }
          ]
        }

record 2:

 "_source" : {
      "working_hour" : [
        {
          "from" : 6
        },
        {
          "from" : 6
        }
      ]
    }

query:

    "query": {
    "bool": {
      "must": [
        {
          "nested": {
            "path": "working_hour",
            "query": {
              "range": {
                "working_hour.from": {
                  "gte": 5,
                  "lte": 7
                }
              }
            }
          }
        }
      ]
    }
  }

My expected result only "record 2" will be returned. However, record 1 and record 2 return. How can I create a query?

Looks like a candiate for a range field?

This is working well:

DELETE test
PUT test
{
  "mappings": {
    "_doc": {
      "properties": {
        "working_hour": {
          "type": "nested",
          "properties": {
            "from": {
              "type": "long"
            }
          }
        }
      }
    }
  }
}
PUT test/_doc/1
{
  "working_hour": [
    {
      "from": 3
    },
    {
      "from": 6
    }
  ]
}
PUT test/_doc/2
{
  "working_hour": [
    {
      "from": 6
    },
    {
      "from": 6
    }
  ]
}
GET test/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "nested": {
            "path": "working_hour",
            "query": {
              "range": {
                "working_hour.from": {
                  "gte": 3,
                  "lte": 4
                }
              }
            }
          }
        }
      ]
    }
  }
}

The response is:

{
  "took" : 59,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 1,
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "test",
        "_type" : "_doc",
        "_id" : "1",
        "_score" : 1.0,
        "_source" : {
          "working_hour" : [
            {
              "from" : 3
            },
            {
              "from" : 6
            }
          ]
        }
      }
    ]
  }
}

Sorry, I made a typo mistake the query should be the following:

{
  "query": {
    "bool": {
      "must": [
        {
          "nested": {
            "path": "working_hour",
            "query": {
              "range": {
                "working_hour.from": {
                  "gte": 5,
                  "lte": 7
                }
              }
            }
          }
        }
      ]
    }
  }
}

And expect record 2 return only

And expect record 2 return only

I presume that's the "contains" operator then if you use the new range field.
It will be more efficient to execute and easier to express these sorts of queries.
