Filter for agent roles entitled "Author" but includes any role
In the filter selection the heading “Author” is misleading, as the filed contains any other specified agent role, e.g. “editor.” See for example this edition item
The “authors” I can filter for include the editors.
I would have expect a filter for any of the roles tgmd:edition/tgmd:agent/@role
given in a tg-search hit list and appropriate headings.
