.Net Nest中的ElasticSearch过滤器聚合(ElasticSearch Filter Aggregation in .Net Nest)

 我正在尝试通过Nest 2.3.2对ElasticSearch运行以下Filter Aggregation查询。 
 
GET workitems_v2/mail/_search
{
  size:0,
  "aggs" : {
    "AutoComplete" : {
      "filter" : { "match": { "claimData.claimOwner":"dav" } },
      "aggs": {
        "Suggestions": {
          "terms": {"field":"claimData.claimOwner.raw"}
        }
      }
    }
  }
}
 
 这是我在Nest（VB.Net）中的内容 - 注意第二个Aggregations（）函数是Filter（）函数的子函数。 
 
Dim queryResults = elasticClient.Search(Of Mail)(Function(s) s.
    Size(0).
    Aggregations(Function(a) a.
        Filter("AutoComplete", Function(f) f.
            Filter(Function(ff) ff.
                Match(Function(m) m.
                    Field("claimData.claimOwner").
                    Query("dav")
                )
            ).
            Aggregations(Function(aa) a.
                Terms("Suggestions", Function(t) t.
                    Field("claimData.claimOwner.raw")
                )
            )
        )
    )
)
 
 但是Nest生成的查询看起来像： 
 
POST /workitems_v2/mail/_search
{
    "size" : 0,
    "aggs" : {
        "Suggestions" : {
            "terms" : {
                "field" : "claimData.claimOwner.raw"
            }
        },
        "AutoComplete" : {
            "filter" : {
                "match" : {
                    "claimData.claimOwner" : {
                        "query" : "dav"
                    }
                }
            }
        }
    }
}
 
 ......这不能给我我想要的东西。 如何告诉Nest“建议”聚合是第一个Filter Aggregation的一部分？ 

I'm trying to run the following Filter Aggregation query against ElasticSearch via Nest 2.3.2.
 
GET workitems_v2/mail/_search
{
  size:0,
  "aggs" : {
    "AutoComplete" : {
      "filter" : { "match": { "claimData.claimOwner":"dav" } },
      "aggs": {
        "Suggestions": {
          "terms": {"field":"claimData.claimOwner.raw"}
        }
      }
    }
  }
}
 
Here's what I have in Nest (VB.Net) - note how the second Aggregations() function is a child of the Filter() function.
 
Dim queryResults = elasticClient.Search(Of Mail)(Function(s) s.
    Size(0).
    Aggregations(Function(a) a.
        Filter("AutoComplete", Function(f) f.
            Filter(Function(ff) ff.
                Match(Function(m) m.
                    Field("claimData.claimOwner").
                    Query("dav")
                )
            ).
            Aggregations(Function(aa) a.
                Terms("Suggestions", Function(t) t.
                    Field("claimData.claimOwner.raw")
                )
            )
        )
    )
)
 
But the query that Nest generates looks like:
 
POST /workitems_v2/mail/_search
{
    "size" : 0,
    "aggs" : {
        "Suggestions" : {
            "terms" : {
                "field" : "claimData.claimOwner.raw"
            }
        },
        "AutoComplete" : {
            "filter" : {
                "match" : {
                    "claimData.claimOwner" : {
                        "query" : "dav"
                    }
                }
            }
        }
    }
}
 
... which doesn't give me what I want. How do I tell Nest that the "Suggestions" aggregation is part of the first Filter Aggregation?
