It would be nice to be able to do one-off searches through a particular type of resource without having to create a collection for them. For example I'm curious which versions of the Bible I have contain the Apocryphal books, so I want to do a search for, say, "Esdras" in all resources with type:Bible. There's no way to do that, except by creating a collection. I shouldn't have to create a collection for each of the simple type rules. That type:Bible syntax should work wherever a collection name is called for.
