I'm having trouble putting together a topical collection of my resources focused on eschatology, end times, last things, rapture, and so forth. When I'm putting a formula in, I know there are resources that aren't showing up. And when I'm working on the formula, as I type resources that once appeared are disappearing (that should be in there). So I'm not doing something correctly when putting the rule in for the new collection.
Anyone have a rule suggestion for pulling together resources on this topic? (I tried looking at the tutorials, but I can't seem to find my mistake.)
