1. Create a composite field (give it lookup name #AA) containing ``{series}/{series_index} - {title}``. If
the series is not empty, then this template will produce `series/series_index - title`.

2. Create a composite field (give it lookup name #BB) containing ``{#genre:ifempty(Unknown)}/{author_sort}/{title}``.
This template produces `genre/author_sort/title`, where an empty genre is replaced with `Unknown`.
