Is there a way to have stored query set to find folders and docx (1st level only, not in subfolders) ?
Excellent, many thanks 
You know if it's possible to do this with Windows Search ?
It'd look like this:
ext:docx OR kind:folder
but I don't know how to exclude subfolders.
Well, why use Windows Search anyway?
Because it's indexed but mostly because I tried for hours without success
