Spring弹性搜索获取嵌套对象值

Question

我正在使用带有弹性搜索的Spring。我有两个对象：

@Document(indexName = "user")
public class user {

    // unique id of client
    @Id
    private Long id;

    //The email of the user
    private String email;

    @Field(type = FieldType.Nested, includeInParent = true)
    private List<Company> companyList = new ArrayList<>();

}

和

public class Company {

    private Long companyId;

    //The name of the company
    private String name;

        private String city;
    }

在没有用户ID的情况下，如何通过ID获得公司的名称？
谢谢
