I have a simple to describe but seemingly hard to resolve problem in SharePoint Online 365.

I have a library with a lot of folders and subfolders, and in these folders are located documents. I started tagging them with Enterprise Keywords in order for my users to search them more easily.

My next step is to be able to create smart folders (or views), for example: a folder called "Strategy", in which all documents located in my subfolders tagged with the Enterprise Keyword "Strategy" appearing in it.

I tried creating a view that filters on keywords, but the folder remains empty.

I'd be very glad to hear from you if you have any idea, and thanks in advance for any help.
