Question about tags

ok i am confused i created a tag white Lantern variant 1:10. added my 12 comics to it. i search for such tag and all 12 show up.

created another tag first sept 1968 tagged the comics went to search like i did with previous tag and 0 issues shown i see the comics with the tag in the tags category. so i managed lists changed it to September birthday and still when i search no results. not sure if what i am doing wrong.

How do you do the search?
The way to do it would be Tag folders.
