Размер не работает с композитными агрегатами в эластичном поиске

У меня следующий запрос: 

GET index_name/_search
{
  "size": 0, 
  "aggs": {
    "my_buckets": {
      "composite": {
        "size": 100,
        "sources": [
          {
            "field1": {
              "terms": {
                "field": "field1"
              }
            }
          },
          {
            "field2": {
              "terms": {
                "field": "field2.raw"
              }
            }
          },
         {
            "field3": {
              "terms": {
                "field": "field3"
              }
            }
          },
          {
            "field4": {
              "terms": {
                "field": "field4.raw"
              }
            }
          },
          ...
          {
            "field7": {
              "terms": {
                "field": "field7"
              }
            }
          }
        ]
      },
      "aggregations": {
        "hits": {
          "top_hits": { 
            "size": 100, 
            "_source": {
              "includes": "field10"
            }
          }
        }
      }
    }
  }
}

Но результат имеет только 8 сегментов и ключ после. Я предполагаю, что после того, как ключ говорит, что у нас есть больше результатов. В таком случае, почему он не получен в том же запросе? Разве размер не определяет количество сегментов, которые я ожидаю от результатов агрегации?

Ниже приведен мой ответ:

Чего мне здесь не хватает?
