C# Elasticsearch嵌套Demax Morelike此查询形成空json字符串

我想使用NEST库在Elasticsearch上使用更相似的查询，并为每个匹配提供不同的提升值

var moreLikeThis = _elastic.Search<Report>(s => s
    .From(0)
    .Size(10)
    .Query(q => q
        .Filtered(f => f
            .Query(fq => fq
                .Dismax(dmx => dmx
                    .TieBreaker(0.7)
                    .Queries(qr => qr
                        .MoreLikeThis(mlt => mlt
                            .OnFields(of => of.Title.Suffix("stemmed"))
                            .MinTermFrequency(1)
                            .MaxQueryTerms(12)
                            .Boost(20)
                            .Documents(docs => docs
                                .Document()          // This is the part where I'm stuck
                            )
                        ), qr => qr
                        .MoreLikeThis(mlt => mlt
                            .OnFields(of => of.Title.Suffix("synonym"))
                            .MinTermFrequency(1)
                            .MaxQueryTerms(12)
                            .Boost(10)
                        )
                    )
                )
            )
        )
    )
);

这就是我作为JSON使用的查询，它工作得很好

{
  "from": 0,
  "size": 10,
  "fields": ["Title"],
  "query": {
    "filtered": {
      "query": {
        "dis_max": {
          "tie_breaker": 0.7,
          "queries": [
            {
              "more_like_this": {
                "fields": ["Title.stemmed"],
                "docs": [
                  {
                    "_index": "test",
                    "_type": "reports",
                    "_id": "68753"
                  }
                ],
                "min_term_freq": 1,
                "max_query_terms": 12
              }
            }, {
              "more_like_this": {
                "fields": ["Title.synonym"],
                "docs": [
                  {
                    "_index": "test",
                    "_type": "reports",
                    "_id": "68753"
                  }
                ],
                "min_term_freq": 1,
                "max_query_terms": 12
              }
            }
          ]
        }
      }
    }
  }
}

中的文档没有解释或给出如何完成此操作的基本概念

谢谢。

如评论中所述，这是一个bug，将与1.5.2 NEST版本一起修复

看起来像只虫子。此问题的PR在这里@Rob Well谢谢您，先生，希望dev能解决它。：）@罗伯：也许你可以把你的评论作为答案提交给我，这样我就可以投票并将其标记为接受？没关系。谢谢：）
