The Scorpion and the Frog
There is always 'The Scorpion and the Frog' pattern we have learned to defend against, so we must be patient. Microsoft will destroy search for us again, scorpions just can't resist their nature.
Because Microsoft has a very long track record with its useless search products. Back in the XP days we learned to abstract ourselves from Microsoft's search incompetence by using alternatives. Not sure if filelocatorlite is still any good because my installers go back to 2012, but the older versions find everything without fuss and without spying on its users, there was zero telemetry in the 2012 installers. The older versions even have a regX search for both files and contents.

Though MS search might for now prioritize local results, I suspect every search location + search-term will be sent to Microsoft's servers for logging, along with your unique machine ID. Thus, adding to Microsoft's ever expanding profile of your digital life. I don't use Win 11 and never will (I barely use Win 10 iot for work), but a simple network analysis might prove this out. To do so, you won't even need wireshark or a firewall tcpdump. Just position yourself near your switch and watch the switch blink pattern. When you click "search", I'd be wiling to wager the next round on me, that you will reliably note switch light activity. This happens with a lot of MS product, which is an indicator your box needs further blocking. Extra credit if you note the switch blink pattern matches your typing. If it does, more than likely, it is Microsoft running a keystroke logger in this product.
A well setup OS emits near zero network activity until the user calls on a network resource. Near zero is possible even with Windows, but requires more effort compared to the many more privacy respecting OSes. And don't get me wrong, I love the older versions of Windows and will always use the three OSes I love: a locked down Windows 7 SP1 with near zero updates, BSD (the best OS ever), and Debian. But after Win 7, Microsoft has not produced an OS worthy of effort to control.
