Search for non-text documents

Hi All,
I’d like to make a “collection” with only those items that are not text. So, for example, a collection that would contain only PDFs, Images, etc. I can’t seem to make the search function do that, unless I tag those file ahead of time with some keyword/status I can search for. Is there a different way to do this?
Thanks!

I’m afraid there is no way to do that, no. You can limit a search collection to only items inside the Draft folder, but there is no way of specifying document types.

All the best,
Keith
