Taking a random guess, maybe Spotlight isn't indexing the Shared folder for her for some reason ?
Yes, that was my idea too. But I can't seem to find where I can point Spotlight to this folder specifically. I did find where I can
exclude it from a search though, but that's the opposite of what I want.
Also, I've learned that there seems to be a difference between the search via Spotlight (top right of the screen) and the search in Finder. In general, Spotlight tends to find a lot more stuff than finder does (but not in this case sadly).
Googling for this is hard, as all the results returned are about Spotlight and shared network drives
Indeed. I've noticed this very same thing.
Not that Windows search is any better, I end up using Agent Ransack to search for files on Windows.
That's also one of the suggestions I found through Google: somebody said to use a different search program. If I don't find the issue, I might as well go with that. Shame though...
