Elasticsearch非规范化数据查询

Question

我还没有找到任何关于关系数据的弹性搜索的例子。

例如：

{
    part: {
        -KbH7E4YBTHvpRVo17P4: {
            description: "Macbook Pro Late 2016 3.3 GHZ"
            id_category: "-KbEGUZU9In8XcWOtNbu"
            id_subcategory: "-KbEGVWkmvycYEAiHAEj"
            manufacturer: "Apple"
        }
    },
    category: {
        -KbEGUZU9In8XcWOtNbu: {
            name: "Computer"
        }
    },
    subcategory: {
        -KbEGVWkmvycYEAiHAEj: {
            name: "Laptop"
        }
    }
}

如何创建一个查询，该查询采用搜索字符串并能够搜索零件，类别和子类别并返回找到的零件。因此，如果他们搜索＆＃34; app＆＃34;制造商会回应一下。如果他们输入＆＃34; comp＆＃34;该类别将命中，该部分将被退回。与子类别相同。

使用firebase数据库，他们强烈反对嵌套数据，所以我已经对所有内容进行了非规范化，但似乎弹性搜索网站上的每个示例都是嵌套数据。

我知道我可以将类别和子类别名称添加到其中，但如果它们发生变化，我必须跟上它们。

我在partItems中遇到了同样的问题，其中每个部分有多个partItems，并且这些问题链接到part和order，所以我需要将part和partItems分开。

这是映射：
