ElasticSearch版本为7.4.2
我在Elasticsearch上很烂，我想弄清楚这个查询有什么问题。

{
  "size": 10,
  "from": 0,
  "query": {
    "bool": {
      "must": [
        {
          "exists": {
            "field": "firstName"
          }
        },
        {
          "query_string": {
            "query": "*",
            "fields": [
              "params.display",
              "params.description",
              "params.name",
              "lastName"
            ]
          }
        },
        {
          "match": {
            "status": "DONE"
          }
        }
      ],
      "filter": [
        {
          "term": {
            "success": true
          }
        }
      ]
    }
  },
  "sort": {
    "createDate": "desc"
  },
  "collapse": {
    "field": "lastName.keyword",
    "inner_hits": {
      "name": "lastChange",
      "size": 1,
      "sort": [
        {
          "createDate": "desc"
        }
      ]
    }
  },
  "aggs": {
    "total": {
      "cardinality": {
        "field": "lastName.keyword"
      }
    }
  }
}

它会传回：

"aggregations": {
        "total": {
            "value": 429896
        }
    }

因此，大约有430k个结果，但是在分页时，我们在426k标记附近停止得到结果。

{
  "size": 10,
  "from": 427000,
...
}

我得到：

{
    "took": 2215,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": {
            "value": 10000,
            "relation": "gte"
        },
        "max_score": null,
        "hits": []
    },
    "aggregations": {
        "total": {
            "value": 429896
        }
    }
}

但是如果我把from改为426000，我仍然得到结果。
