在 ElasticSearch 中使用组合字段作为 id 映射 [英] Using a combined field as id mapping in ElasticSearch

问题描述

从这个问题我可以看出可以使用现有字段作为id在弹性搜索中

From this question I can see that it is possible Use existing field as id in elasticsearch

我的问题是，是否可以做类似的事情但连接字段.

My question is, if can do similar thing but concatenating fields.

{
"RecordID": "a06b0000004SWbdAAG",
"SystemModstamp": "01/31/2013T07:46:02.000Z",
"body": "Test Body"
}

然后做类似的事情

{
  "your_mapping" : {
      "_id" : {
          "path" : "RecordID" + "body"
     }
 }
}

因此 id 是通过连接这些字段自动形成的.

So the id is automatically formed from concatenating those fields.

推荐答案

不，你不能，你只能让 _id 指向文档中的一个字段，如果需要，也可以使用点符号(例如 level1,level2.id).

No you can't, you can only make the _id point to a field that's within the document, using the dot notation as well if needed (e.g. level1,level2.id).

我建议在您的文档中有一个包含整个 id 的字段，或者甚至更好地将 id 取出并在 url 中提供它，因为配置路径会导致在不需要时解析文档.

I'd suggest to have a field that contains the whole id in your documents, or even better to take the id out and provide it in the url, as configuring a path causes the document to be parsed when not needed.
