Elasticsearch NEST 查询的行为与 Kibana Dev Tools 中的等效查询不同

Question

我正在尝试针对我的索引构建一个查询，该查询将使用 function_score 来提升字段具有特定值的记录。在 Kibana Dev Tools 中，我有以下查询 returns 3 按预期命中：

GET /myindex/_search
{
  "query": {
    "function_score": {
      "query": {
        "multi_match": {
          "query": "somename",
          "fields": ["licenseName", "businessName"]
        }
      }
    }
  }
}

但是当我尝试用 NEST 重现它时，没有过滤发生，它只是 returns 索引中的所有记录。对我来说这看起来是一样的，但我一定遗漏了一些东西：

var byNameSearchResult = await _elasticClient.SearchAsync<MyModel>(sr => sr
    .Index("myindex")
    .Query(qcd => qcd
        .FunctionScore(fsqd => fsqd
            .Query(fsqcd => fsqcd
                .MultiMatch(mmqd => mmqd
                    .Query(message.Name)
                    .Fields(fd => fd
                        .Field(f => f.LicenseName)
                        .Field(f => f.BusinessName)
                    )
                )
            )
        )
    )
);

ETA：这是 DebugInformation 输出：

对于我在 NEST 查询中遗漏的内容有什么想法可以使它像 Dev Tools 中的原始查询一样运行吗？

Answer 1

我想我找到了答案。来自 function_score 的文档：

To use function_score, the user has to define a query and one or more functions, that compute a new score for each document returned by the query.

因此，与我在 Dev Tools 中的手动查询不同，我向 NEST 查询添加了一个函数：

var byNameSearchResult = await _elasticClient.SearchAsync<MyModel>(sr => sr
    .Index("myindex")
    .Query(qcd => qcd
        .FunctionScore(fsqd => fsqd
            .Query(fsqcd => fsqcd
                .MultiMatch(mmqd => mmqd
                    .Query(message.Name)
                    .Fields(fd => fd
                        .Field(f => f.LicenseName)
                        .Field(f => f.BusinessName)
                    )
                )
            )
            .Functions(sfd => sfd
                .Weight(wfd => wfd
                    .Filter(wfqcd => wfqcd
                        .Term(tqd => tqd.Field(tqd => tqd.AccountId).Value(accountId))
                        )
                    .Weight(100)
                    )
                )
            )
        )
);

我得到了我期望的查询和结果：
