我想向已经包含文档的现有索引添加一个新属性。
原始文件

[ElasticsearchType(Name = "mydocument", IdProperty = nameof(Id))]
public class MyDocument
{
    public Guid Id { get; set; } = Guid.NewGuid();

    [Date(Name = "occurredon")]
    public DateTime OccurredOn { get; set; }

    [Text(Name = "details")]
    public string Details { get; set; }
}

索引是如何初始化和填充的。。。

var client = new ElasticClient(settings);
var createResponse = client.CreateIndex("myindex", d => d.Mappings(ms => ms.Map<MyDocument>(m => m.AutoMap())));

// index many documents...
var docs= new List<MyDocument>();
docs.Add(new MyDocument { OccurredOn = DateTime.UtcNow, Details = "foo1" });
docs.Add(new MyDocument { OccurredOn = DateTime.UtcNow, Details = "foo2" });
var indexResponse = await client.IndexManyAsync(docs, "myindex");

现在我想通过添加“collector”属性来更新文档。新文档将如下所示。。。

[ElasticsearchType(Name = "mydocument", IdProperty = nameof(Id))]
public class MyDocument
{
    public Guid Id { get; set; } = Guid.NewGuid();

    [Date(Name = "occurredon")]
    public DateTime OccurredOn { get; set; }

    [Text(Name = "details")]
    public string Details { get; set; }

    // new property
    [Text(Name = "collector")]
    public string CollectionHost { get; set; }
}

我必须发出什么一次性命令才能添加新的“collector”属性？我试过了，但失败了。

var z = await client.MapAsync(new PutMappingRequest("myindex", typeof(MyDocument)));

我相信这是可以做到的，但也许不是用nest，我需要用一个较低级别的api来实现？
