Anything to do to get RediSearch to search across clusters?

I’m the author of a Redis client in Crystal that supports both clustering and various Redis Stack modules, including RediSearch, and I’m wondering if there’s anything that needs to be done for RediSearch to search across clusters or if the RediSearch module on clusters will handle this automatically.

My confusion about this stems from the fact that RSCoordinator hasn’t had any meaningful updates in 9 months, and this issue comment says it’s been rolled into RediSearch. But I can’t find any documentation on it and the FT.CREATE documentation still mentions it:

Mainly, I want to know if my Redis client needs to accommodate RSCoordinator on clusters and, if so, what commands (or updates to existing commands) I need to add for it.
