Searching OneDrive files for content in File Explorer when files in "Online Only" mode

Lou_Mickley  Obligatory: First check that you have File Contents checked under Search Options on the Explorer menu. I note though that Windows 11 doesn't really pay strict attention to these settings as it returns search results from Zipped folders even when that option is off.

OneDrive search is very slow and anaemic compared to Dropbox, which has a far faster and more powerful search built into its desktop client.  Even after months of installation, when I run search on OneDrive content, Windows starts downloading every file to index despite my having Cloud Search enabled.

So, no you're not really missing anything. Microsoft are currently too focussed on turning OneDrive into a pale Instagram clone to bother with bread and butter search and filtering.
