Will the persistent indices still be built on ART indexes? ART is a great choice of data structure. Fast lookups, range queries and prefix queries.

Typesense DB (Typesense.org) under the hood also uses ART as the base datastructure for fast full text search queries.

So I assume it would be straightforward to build an text search engine on top of duck DB and utilize ART indices to do even more lovely things.
