我将NEST与具有属性的类配对使用来推送新文档。
这是我定义类的方法:
public class PatientNestModel
{
[Text]
public string FirstName { get; set; }
[Text]
public string LastName { get; set; }
[Text]
public string MiddleName { get; set; }
[Date(Format = "dd-MM-yyyy")]
public DateTime BirthdayDate { get; set; }
[Keyword]
public string Gender { get; set; }
[Text]
public string Phone { get; set; }
[Nested]
public List<AdditionalContact> AdditionalContacts { get; set; }
[Boolean]
public bool Active { get; set; }
}
这是我的推送方式:
var response = _esClient.Index(model, idx => idx.Index("patients_esindex"));
但是，然后我的索引元数据看起来带有关键字类型。
{

}
}
但是，只有当我将术语与
.keyword一起使用时，我才能通过文本搜索找到所需的文档我做错了什么？
最佳答案
从ES 5.0开始，字符串字段已分为两种新类型:应该用于全文搜索的文本和应该用于关键字搜索的关键字。

关于c# - ElasticSearch:为什么索引中的所有文本字段都具有关键字类型？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53586989/
