Using a combined field as id mapping in ElasticSearch

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

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

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

And then do something like

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

So the id is automatically formed from concatenating those fields.

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).

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.
