Changing TTL of all documents in an index?

Elastic Stack Elasticsearch
1

What's the best way to change the TTL of all documents already written in
an index? Can up just update the TTL or do I have to re-index everything?

I was thinking that if I have to update the TTL often maybe I just write a
manual garbage collector and do my own cleanup.

You can set the same TTL for all docs in an index -

If you're updating the TTL often, then perhaps using time based indexes
would be a better idea? TTL is resource heavy.
