C# 如何用C区分ElasticSearch中的字段（搜索结果中有多个重复项）？

我试图从elasticsearch服务器获取/搜索结果。但我只有获取权限，所以我无法将一些映射索引放入ES服务器或更改ElasticSarch中的任何配置

…/testindex/doc/\u search？q=country\u代码：99&size=5000&pretty

我尝试创建新索引，但已经失败了，因为我没有任何权限

我还尝试了以下代码：

并且不返回存储桶或文档计数：[0]

我在ElasticSearch中也需要伪SQL代码

从testindex中选择*不同的所有者代码，其中国家/地区代码=99

所以我应该得到这些结果Mike-Brown-555-99，John-Smith-444-99。。并忽略具有相同所有者代码的其他结果。名称和/或姓氏字段不同并不重要。我想区分所有者代码字段并搜索countryCode字段。在SQL查询中很容易做到，但在ElasticSearchV6.x中我非常困惑

提前谢谢

您能否共享result.DebugInformation中的信息以及您使用的elasticsearch和NEST的哪个版本？您能否共享映射到。还可以共享CustomDToC类，非常确定您的类与es映射不匹配。
