Sorting on empty field

Bryonie · 01-18-2015, 01:27 PM

Hi,
I'm a long term user of Calibre, but I've something I want to do that I can't figure out. Is it possible to sort a field/column on whether it's empty or not? I want to find all the books that have no comments so that I can get summaries for them.
Thanks
Bry

@Bryonie - search for comments:false. That search works for any column, e.g. pubdate:false will find all books with no Published date, publisher:true will find all books with a Publisher.
