Use existing field as id in elasticsearch

Question

Just started using elasticSearch today. I was wondering if it would be possible to set in some kind of global parameter to use a certain field within a document as the ID always?

My JSON documents will always have it's own unique ID

{
  "Record ID": "a06b0000004SWbdAAG",
  "System Modstamp": "01/31/2013T07:46:02.000Z",
  "body": "Test Body"
}

Here I would like to use Record ID as the ID field.

Regards

You want to use the path setting, see the docs here:

http://www.elasticsearch.org/guide/reference/mapping/id-field/

specifically something like this should work in your mapping:

{
    "your_mapping" : {
        "_id" : {
            "path" : "Record ID"
        }
    }
}

I've never tried having variable names split up though. You might want to camelcase or underscore them if you run into wierdness.
