ネストしたアグリゲーションがAggregationContainerと連携していません

Question

ネストされたアグリゲーションに問題があります。ここで私が集計を定義する方法と私が得るjson同等物を得る：

var aggregations = new AggregationDictionary(); 

var nestedAgg = new AggregationContainer 
{ 
    Nested = new NestedAggregation("some_name1") 
    { 
    Path = "users", 
    Aggregations = new TermsAggregation("some_name2") 
    { 
     Field = "users.name.keyword", 
     Size = 100, 
     Order = new List<TermsOrder> { new TermsOrder() { Key = "_term", Order = SortOrder.Descending } } 
    } 
}; 

aggregations[aggKey] = nestedAgg; 

searchRequest.Aggregations = aggregations; 

上記はjsonに変換されています。それだけでパスなし集計定義を示しています。直接AggregationDictionaryとAggregationContainerを使用して

{ 
    "aggs": { 
    "some_name1": { 
     "nested": { 
      "path": "users" 
      } 
    } 
} 

Answer 1

は少し厄介です。私たちはタイプAggregationContainerの変数にNestedAggregationを割り当てるためにAggregationContainerにAggregationBaseから暗黙の変換（集計から派生ベースクラス）を使用するここでは、この

var aggregations = new AggregationDictionary(); 
var aggKey = "some_name1"; 

AggregationContainer nestedAgg = new NestedAggregation("some_name1") 
{ 
    Path = "users", 
    Aggregations = new TermsAggregation("some_name2") 
    { 
     Field = "users.name.keyword", 
     Size = 100, 
     Order = new List<TermsOrder> 
     { 
      new TermsOrder() { Key = "_term", Order = Nest.SortOrder.Descending } 
     } 
    } 
}; 

aggregations[aggKey] = nestedAgg; 

var searchRequest = new SearchRequest<Test>(); 

searchRequest.Aggregations = aggregations; 

client.Search<Test>(searchRequest); 

のようにこれを行うことができます。なぜ `AggregationDictionary`と` AggregationContainer`直接ぎこちないを使用している

This implicit conversion also sets the Aggregations and Meta properties on AggregationContainer, which is why your original attempt doesn't quote work correctly.
