Search: Find books with a top-level tag
Just curious:

With a hierarchical column, is there a way to search for any books that contain the top level of an undefined value?

Book 1: foo, foo.bar
Book 2: foo.bar, test.123
Book 3: test

Since book 1 and 3 both have top-level tags, I want the search to match those, but not book 2.

I hope I explain this clear enough.

Question: Any obvious mistakes here? It's green, but not turning up results.

The regular expression contains spaces so it is interpreted as multiple queries. Use quotes to fix it.
Code:
tags:"~^[^\.]+$" AND NOT tags:"~(Comics|Documentation & Manuals|Fanfiction|Fiction|Magazines & Periodicals|Nonfiction)"
It is a good idea to always quote the query part of an expression. (fieldname:"query")
