使用 NEST 为同一文档批量添加嵌套对象

问：

我在 Elastic Search 中有一个带有此映射的索引：

{
  "properties": {
    "allSubjects": {
      "type": "nested",
      "properties": {
        "nuis": {
          "type": "text",
          "fields": {
            "keyword": {
              "ignore_above": 256.0,
              "type": "keyword"
            }
          }
        },
        "dateOfInspection": {
          "type": "date"
        }
      }
    },
    "iD": {
      "type": "keyword"
    }
  }
}

嵌套对象将有超过 300K 行。但是当我尝试添加它时，会出现以下错误：

Invalid NEST response built from a unsuccessful (413) low level call on PUT: 

我曾想过这样做。我想用 10K 将 300K 对象分成更小的批次，然后为同一个文档逐个添加。但是当我尝试这样做时，它只保存了最后一批，因此它覆盖了它们。 我尝试为第一批创建文档，然后使用以下命令更新文档：

public bool AddToElasticObjectsBulk(SobElastic sobElastic)
{
    var chunks = sobElastic.AllObjects.Chunk(10000);

    if (chunks.Count() > 1)
    {
        var indexResponse = _elasticClient.Index(new SobElastic()
        {
            ID = sobElastic.ID,
            AllObjects = chunks.ElementAt(0).ToList()
        }, d => d.Index("my-obj"));
    }

    var leftChunks = chunks.Skip(1);
    for (int i = 0; i < leftChunks.Count(); i++)
    {
        var sobElastic1 = new SobElastic()
        {
            ID = sobElastic.ID,
            AllObjects = leftChunks.ElementAt(i).ToList()
        };
        var bulkResponse = _elasticClient.IndexDocument(sobElastic);// this is wrong i know but here is where i need help 
    }
    return true;
}
