英文:
GetById of an index in Elastic search through NEST client
问题
我有一个名为UserModel.cs的模型：
public class UserModel
{
public string Id { get; set; }
public string Name { get; set; }
public string Age { get; set; }
}
当我尝试使用用户的userID进行搜索时，无法获取用户：
var clientProvider = new ElasticClientProvider();
var response = await clientProvider.Client.IndexAsync(userModel, i => i
.Index("user_index")
.Type("user")
.Id(userModel.Id)
);
return response.IsValid;
在创建记录时，_id是通过Elasticsearch自动生成的，但它存储在_id元字段下，而不是_source下。我无法通过NEST客户端访问_id元字段。
提前感谢。
英文:
I have a model as
UserModel.cs
public class UserModel
{
public string Id{get; set;}
public string Name{get; set;}
public string Age{get;set;}
}
And I am unable to get the User while Searching with his userID.
var clientProvider = new ElasticClientProvider();
var response = await clientProvider.Client.IndexAsync(UserModel, i => i
.Index("user_index")
.Type("user")
.Id(userModel.Id)
);
return response.IsValid;
When I am creating a record the _id is getting auto-generated through elastic Search but it is stored as _id a meta field but not under the _source. And I am unable to access _id of meta field through NEST client.
Thanks in advance

您可以使用Get方法通过ID检索文档。以下是一个示例：
await client.IndexManyAsync(new []
{
new Document{Id = "1", Name = "name1"},
new Document{Id = "2"},
new Document{Id = "3"},
new Document{Id = "4"},
new Document{Id = "5"}
});
await client.Indices.RefreshAsync();
var getResponse = await client.GetAsync<Document>("1");
System.Console.WriteLine($"Id: {getResponse.Source.Id} Name: {getResponse.Source.Name}");
输出：
Id: 1 Name: name1
Document类：
public class Document
{
public string Id { get; set; }
public string Name { get; set; }
}
希望这有所帮助。
英文:
You can retrieve document by id with help of Get method. Here is an example:
await client.IndexManyAsync(new []
{
new Document{Id = "1", Name = "name1"},
new Document{Id = "2"},
new Document{Id = "3"},
new Document{Id = "4"},
new Document{Id = "5"}
});
await client.Indices.RefreshAsync();
var getResponse = await client.GetAsync<Document>("1");
System.Console.WriteLine($"Id: {getResponse.Source.Id} Name: {getResponse.Source.Name}");
Prints:
Id: 1 Name: name1
Document class:
public class Document
{
public string Id { get; set; }
public string Name { get; set; }
}
Hope that helps.
