Searching for the absence of a tag?

TMF · 08-29-2009, 01:15 PM

Is there a way to construct a search query that matches all books that do not have a certain database field set, such as all books without an ISBN? (I vaguely remember reading about it somewhere, but can't find it again.)

If there is a way to do this, it should probably be described at http://calibre.kovidgoyal.net/user_m...ml#search-sort. Thanks!

Click the little advanced search button to the left of the search box

Thanks, but I'm not sure what you mean. Using that function I can make searches of the type "not xxx". But this does not work for filtering out books that have a certain field not set, such as e.g. no ISBN or no series.

isbn:false or series:false
