Time series index clarification

Query regarding index utilisation

  1. I see there’s a default index being created when a time series collection is created and the nature is that of a compound index

  2. is it possible to create another index in this time series collection?

  3. when I do an explain of a query selecting records in this collection, I see index pattern is clustered_index pattern

But, I need it to be dedicatedly utilising time series index ,which aligns to my usecase.

  1. Is it possible to select the index utilisation incase a collection has two indexes for faster data retrieval?

Apologies if my query is too novice level. Needed to understand a bit more
