I have windows 10, btw.
I'm trying to search for files in my documents folder (not in OneDrive) using Cortana, but whatever I search, the only documents that show up after a while are ones on my OneDrive that are vaguely related. For example, I'm looking for a pdf titled "usermanual.pdf", which is on my PC, but Cortana can't find it. I don't even think she looks there.
I've been looking for a fix for weeks about this problem, and the only solution I could find is to re-index. I've indexed the entire C:, to no positive result.
Apologies if I haven't provided enough information.
