Any way to modify the elasticsearch index?

[dan]

Is there any way to configure the Elastic Search index through the API or by altering environment variables or mounting a config via volume in docker?

I try to achieve autocomplete-suggestions based on a search query over multiple user-fields. The only solution seems to be to create separate mappings in the elasticsearch index.

I could probably update indexes directly in elasticsearch from my app with PUT, but what happens when I press REINDEX in fusionauth?

When you re-index, we delete our named index and rebuild it.

You would probably be better off creating your own index.
