Ok gave this a try. Actually pretty handy. I wish I didn't clean up my Windows PC so I could compare indexing of files, but it did a good job of finding most things but the things I searched for Windows was able to find too. But its nice to have an easy shortcut to Google search and also having Google Lens on my PC to translate text, ask questions about a screenshot etc. I love this feature on my android.

The UI is a little annoying at times. Some apps receive the alt+space key so it doesn't always behave like you expect.

Checking Task Manager it used about 43MB of memory whether running as a background process or in the foreground, showing search results.
