Are you sure it doesn't index anything? There is even a section in the settings called Indexes.

Also when you launch it first, it's going to be empty and says it's scanning your folders and it takes a little bit until you see something.

I think it is still indexing (maybe using the MFT instead of recursively listing files and directories), it's just a lot better than Windows search indexing. And it might use this [1] to keep up to date? It's mentioned in the settings

No I'm not sure. Maybe it builds a rudimentary index... but give it a shot yourself and see. 15 seconds after installing, you can search your entire system instantly. It's crazy whatever it is doing.

And yes I do believe it uses the USN Journal to stay up to date.

There's actually a wikipedia page, and it explains how it works. As we suspected, it uses the MFT for initial indexing and change journal for updates.
