field property in Elastic Search

I am trying to re-index my documents in order for them to be sortable which requires making the sortable fields Multi-field properties with a "raw" version of the string which does not get analyzed.

I am following this article, but I am still getting errors when searching my documents with a sorting query.

I have a question then regarding the re-indexing of the data... if I re-index the doucments into this new index, then do I need to have some extra logic to set the analyzed version and the non_analyzed or "raw" version of the string as well? Or does elastic search automatically fill that one? Here is what my field looks like:

{
    "entityName": {
        "type":"string",
        "fields": {
            "raw": {
                "type":"string",
                "index":"not_analyzed"
            }
        }
    }
}

So when I index a document with a _source like:

{
...
"entityName":"Ned Stark"
...
}

Will the mapping to both the analyzed field and the not_analyzed field complete or is there something else I have to do to tell the indexing to fill in the "raw" property as well?

No, you don't need to do anything else.

After reindexing your documents, you must tell which fields the query should use like in your given documentation article.

Raw subfield:

POST /_search
{
    "query": {
        "match": {
            "entityName.raw": "foo-bar"
        }
    }
}

or original analysed type:

POST /_search
{
    "query": {
        "match": {
            "entityName": "foo-bar"
        }
    }
}
