Hello, everyone! I have an issue regarding the advanced search “Additional content types for books/printed materials”. Whatever I choose, the message “No results found!” is presented, although the marc21 008 field - 24 - Nature of contents is filled according to the material described. Any thoughts on what the issue could be? I'd appreciate any input!
