For what it's worth... I get this "Tag search not working on Windows desktop version" bug, too - it's annoying / frustrating. And Evernote have known about it since October? I also agree with JBenson2: http://discussion.evernote.com/topic/42921-tag-search-not-working-on-windows-desktop-version/page-2#entry248260 "Evernote's search capability (hesitancy, speed, UI, and overall results) have taken a significant step backwards." - especially on Android. If anyone from Evernote is reading this, please fix the tag bug if you can. Many thanks.
