> Your point works fine for email

I'm not sure it even works there. I have emails both categorized and tagged and still can't find anything between the thousands of work emails I get a week from coworkers, mailing lists, and automated systems. Any search brings up dozens to thousands of results.

> but for documents on my drive tags don't seem like a great approach because at least on my machine even though tagging is an option, it's not robust and reliable.

Not to mention that most users aren't interested in tagging every file they have. I never tag files. My emails can get auto-tagged by mail rules, but I don't have time to add tags to all of my files.
