Updating to 8.15.1 form 8.12.1 and I've noticed the Hit class is id field is now nullable? Why? Is it possible to have docs without and ID? How does that even work?

I did not check but may be it's related to the changes that are happening with the new index mode `logsdb`?  
I'm not sure though 😉

Hello! It's a very specific case: when `stored_fields` is set to `none` on a search request, the result contains no `_id` field. More info on `store` [here in the docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-store.html).
