在 .net 上通过字符串数组 elasticsearch 进行查询

如何解决在 .net 上通过字符串数组 elasticsearch 进行查询

我有一个这样的数据结构。我将通过国家/地区 ID 列表进行查询，以获取 C# 中的查询列表中存在的国家/地区 ID 的所有数据 .det

[
  {
    "ProductId": 1,"Name": "Кетчуп Торчин","Category": {
      "Id": 2,"Name": "Приправи,соуси,спеції","Description": "adasd"
      "ParentCode": 0
    },"Manufacturer": {
      "ManufacturerId": 1,"BrandName": "test1","CountryId": "d15e3020-60b0-11de-be1e-0030485903e1","CountryName": "test country1"
    },"Id": 1
  },{
    "ProductId": 2,"Name": "nescafe","Category": {
      "Id": 17,"Name": "Разное","Description": "adasd","ParentCode": 0
    },"Manufacturer": {
      "ManufacturerId": 2,"BrandName": "test2","CountryId": "d15e3020-60b0-11de-be1e-0030485903e2","CountryName": "test country2"
    },"Id": 2
  }
]

我的查询代码是这样的..:

var filters = new List<Func<QueryContainerDescriptor<ProductForAmazonElasticSearch>,QueryContainer>>();
filters.Add(q => 
        q.Terms(b => b
        .Name("named_query")
        .Boost(1.1)
        .Field(f => f.Manufacturer.CountryId)
        .Terms(countryIds)
        ));

但它返回一个空列表。我的 c# 代码有什么问题吗？
