After looking at the tutorial video I tried searching/filtering the Library using "type: bible" and setting up some tags. That worked ok.
I noticed that the Subjects field already contained words I would use for tags. So I tried filtering the library display with something like "Subjects:Bibles,English" but it didn't work. I also tried filtering by my tags and that didn't work. I couldn't find anything in the help information on the syntax for the Library search field.
Are the key words "Subject" or "Subjects", "Tag" or "Tags"?
What is the syntax for including more than one subject or tag word?
Can anyone give me an example of a multiword filter/search for the Library?
