TermAggregation以及在AggregationDictionary中不起作用的其他TermAggregation

Question

使用NEST，我的请求看起来像这样

var searchRequest = new SearchRequest<T>()
{
...
    Aggregations = new TermsAggregation("field1")
    {
        Field = "field1",
        Aggregations = new TermsAggregation("field2")
        {
            Field = "field2",
        }
    },
...
}

await _elasticClient.SearchAsync<T>(searchRequest)

并且我得到了我期望的结果，对于“ field1”的每个替代项，聚合都在“ field2”上]

我想要其他聚合，因此我将术语聚合放在AggregationDictionary中。

var aggs = new AggregationDictionary();
aggs.Add("field1", new TermsAggregation("field1")
    {
        Field = "field1",
        Aggregations = new TermsAggregation("field2")
        {
            Field = "field2",
        }
    })
...
var searchRequest = new SearchRequest<T>()
{
...
    Aggregations = aggs,
...
}
...
await _elasticClient.SearchAsync<T>(searchRequest)
现在我在“ field1”上获得聚合，但在“ field2”上没有子聚合。

我是否缺少某些东西或应该以这种方式工作？

编辑1：为AggregationDictionary添加了密钥。添加以便我的示例代码（希望）能够编译并包含我的SearchAsync调用

使用NEST，我收到的请求看起来像这样var searchRequest = new SearchRequest （（{... Aggregations = new TermsAggregation（“ field1”）{Field =“ field1”，...

Answer 1

aggs.Add( new TermsAggregation("field1")
    {
        Field = "field1",
        Aggregations = new TermsAggregation("field2")
        {
            Field = "field2",
        }
    })

此代码将不会编译为AggregationDictionary.Add() method signature，因此>
AggregationDictionary.Add()
