在ElasticSearch中将组合字段用作ID映射 [英] Using a combined field as id mapping in ElasticSearch

问题描述

从这个问题中，我可以看到使用现有字段作为ID的可能性在Elasticsearch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，但可以连接字段。

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

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

然后执行类似的操作

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

因此ID是自动

推荐答案

不，您不能，只能使_id指向位于以下字段内的字段文档，并在需要时也使用点符号（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).

建议有一个领域在文档中保留整个id，甚至更好地将id取出并在url中提供，因为配置路径会导致在不需要时对文档进行解析。

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.
