Windows' search has been broken for multiple generations now. Some people inside Microsoft seemingly even know, that's why the PowerToys team created "PowerToys Run." A Windows Search that actually basically functions correctly.
People act like it sudden was broken in Windows 11 when in reality it never worked correctly in 7, 8, 8.1, or 10 either. Instead of fixing it, they've only made it worse. It seems like nobody in Microsoft works on core stuff anymore.
I don't know how but it works beautifully for me on windows 11. What I mean is, I have been using windows for decades and I do not like any changes at all, they are all forced on me. But this change successfully turned me around. I find I rarely use File Explorer/file managers any more and access most applications and documents through the search.
I do remember it sucking on previous versions. I did use winaero tweaker to turn off the web results (and many other annoyances).
Yeah, I've never experienced Windows search ever working. Even on XP, it couldn't find commonly opened folders or programs for me. It always felt like some sort of joke feature just meant to fool me into wasting time.
As far as I remember it was working well in 7 and 8 (deterministic and shows programs that you expect it to show). From 10 it started behaving erratically (same time it got binged but maybe unrelated).
If memory serves, Windows 2000 was the last version where search worked reliably. It was a simple linear search through files which could take a while on larger folders, but was reliable and predictable since it did not rely on a background indexing service which seems to get stale or just plain wrong most of the time.
If I search for “foo”, I’d like to get all files containing “foo” please, without a shadow of a doubt that some files were skipped, including those that I have recently created. I still can’t get that as of Windows 11!
