У меня есть такая структура БД в эластике:

```
[
    {
        "Number": 250,
        "Date": 1606996816
    },
    {
        "Number": 251,
        "Date": 1606997816
    },
    {
        "Number": 251,
        "Date": 1606997816
    },
    {
        "Number": 251,
        "Date": 1606998816
    },
    {
        "Number": 251,
        "Date": 1606999816
    },
    {
        "Number": 251,
        "Date": 1606999816
    }
]

```

возможно ли найти все записи по номеру "Number": 251 с максимальным значением "Date"

```
[
    {
        "Number": 251,
        "Date": 1606999816
    },
    {
        "Number": 251,
        "Date": 1606999816
    }
]
```

Это для поиска в одном документе, а мне нужно из нескольких документов найти все что равны максимальному  
сейчас я делаю так:

```
_search?size=1&pretty=true

{
    "query": {
        "bool": {
            "must": {
                "term": {
                    "Number": 251
                }
            }
        }
    },
    "sort": {
        "Date": "desc"
    }
}

```

Потом беру значение Date и подставляю в новый запрос

```
_search?size=1000&pretty=true

{
    "query": {
        "bool": {
            "must": [
                {
                    "term": {
                        "Number": 251
                    }
                },
                {
                    "term": {
                        "Date": Date
                    }
                }
            ]
        }
    }
}

```

А возможно ли это сделать одним запросом?

Так выглядит ответ с БД:

```
{
    "took": 0,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": 2,
        "max_score": 1.0,
        "hits": [
            {
                "_index": "history",
                "_type": "_doc",
                "_id": "dtmlKHYBDbM9kUrCpwpX",
                "_score": 1.0,
                "_source": {
                    "Card_Number": 251,
                    "End_Date": 1606999743
                }
            },
            {
                "_index": "history",
                "_type": "_doc",
                "_id": "d9mlKHYBDbM9kUrC7Qpe",
                "_score": 1.0,
                "_source": {
                    "Card_Number": 251,
                    "Status_Date": 1606999743
                }
            }
        ]
    }
}
