These are the screenshots from my video on Windows Search, which previously I had never taken the trouble to understand. The link to the video is below the screenshots. This link gives the msdn view on Advanced Query Syntax, which is the supposed proper name for Windows Search. It feels as though Microsoft are just blindly advocating Cortana without understanding there is need to promote their ability to search more specifically just on the desktop. Desktop search is still a use-case.
If you are kind enough to watch the video, well thank you :-).
