End goal is to have the value set in `_id` saved w/ `doc_values` enabled. I'm looking to do this in order to increase sorting performance - where id is used. Regardless of if the \_id values is provided or generated, is there a way to set `doc_values` on this field? If not, is it possible to copy the value of `_id` into another field that does have `doc_values` enabled? Other thoughts ? Running ES version 1.7.5 ---

I was able to do this w/ a transform, setting a newly defined field to the values of \_id on insert. ---
