Here is something that works for me.

The template:

python:
def evaluate(book, context):
	db = context.db.new_api
	items_with_notes = context.globals.get('items_with_notes')
	if items_with_notes is None:
		items_with_notes = db.get_all_items_that_have_notes('authors')
		context.globals['items_with_notes'] = items_with_notes
	for aut in book.authors:
		if db.get_item_id('authors', aut) in items_with_notes:
			return '1'
	return ''

You set which category you are interested in by changing 'authors' to the category name of interest, e.g., tags.

The template search is:


EDIT: This template is slow. See the template in post #10.
