I tried it many years ago and it was nice, but I couldn't really make it fit my workflow properly.
Somewhat related, I run a linux VM with Everything search 1.5 (alpha, beta or rc, I don't remember, but it's much better than 1.4) in Wine, and that VM has most of my main storage array mounted read-only. Then I have the Everything web interface enabled, so I have a place to search my tens of millions of hoarded files instantly. Doesn't archive file content though.
