What it is

Provider for app index?

I believe it is a provider for the settings but can't confirm (I don't have a Xiaomi device).

A lot of people debloat this but I'd like to know more about this one.

Content providers encapsulate data, providing centralized management of data shared between apps.

Commands

adb shell pm uninstall --user 0 com.xiaomi.providers.appindex

To put it back:

adb shell cmd package install-existing com.xiaomi.providers.appindex

Every removal listed here is per-user only: the system image is untouched, and the restore command puts the app back from the copy already on the device. Nothing is downloaded.

This is not the directory. Here we say what a package is in general; what happens on your particular television is on your model's entry, and that one wins. The same package can be dead weight on one set and hold the home screen up on another.
