elasticsearch - 使用NEST更新ElasticSearch中的子对象

Question

我有一个具有以下结构的Elastic Search文档:

{
   "Id": 123,
   "name": "MyName",
   "skill": {
         "skillId": 321,
         "name": "Skill Name",
         "description": "Skill Description"
    } 
}

我还有一个映射到此文档的类:

public class Person {
      public int Id { get; set; }
      public string name { get; set; }
      public Skill skill { get; set; }
}

public class Skill{
      public int skillId { get; set; }
      public string name { get; set; }
      public string description { get; set; }
}

现在，我想更新关于 flex 搜索的技能描述:

var person = _client.Get(.......)
var newSkill = new Skill();
newSkill.skillId = person.skill.skillId;
newSkill.description = "This is a new Description"

var result = _client.Update<Person, Skill>(u => u
            .IdFrom(person)
            .Doc(newSkill)
            .RetryOnConflict(3)
            .Refresh()
        );

此代码不会更新人员的现有技能，而是将“技能”属性添加到人员的根目录。

那这里怎么了？

Answer 1

您正在尝试像使用SQL一样使用ElasticSearch。

您需要将新的Skill分配给Person并更新整个Person对象，如下所示:

var person = _client.Get(.......)
var newSkill = new Skill();
newSkill.name = "New Skill";
newSkill.description = "This is a new Description"

person.skill = newSkill;

var result = _client.Update<Person, Person>(u => u
            .IdFrom(person)
            .Doc(person)
            .RetryOnConflict(3)
            .Refresh()
        );
