How did you generate the fields of this file? I see there are fields that were in the older version of this file but they aren't there anymore.

I cloned grimoirelab repository, used docker-compose and changed the default-grimoirelab-settings/setup.cfg. Used the discover of kibiter to see the fields of the documents.

Hey, @sduenas I did micro.py --raw --enrich --backends stackexchange and checked with kibiter index-patterns. I actually forgot to commit some changes like author_gender and author_gender_acc. I also arranged them alphabetically.
