Possible to search for books without a cover?
Is it possible to search for books without a cover? I know I can search for books with no comments via true|false, but is there a similar search for covers? I've tried cover:false.

Cover:false comes up with exactly 1 book in 691 titles

When I view the comments or cover browser
"My_Catalog" (my name for the catalog that Calibre generates) has only the default (missing cover) showing
I have half a dozen TXT files that have no cover set (default cover shows)

Windows XP 6.40 Calibre
BTW I assume "cover" is part of Comments? I am looking at the file
/opt/calibre/resources/metadata_sqlite.sql
and do not see a table or field for Cover

The CLI version of the command would be:

Code:
calibredb list --search cover:false --fields cover,title
When I execute that I get the same title as when using the GUI search, and it does return a book with 'None' in the cover field. However, it's not the only book in my library without a cover, so clearly it's not working as expected.

I would suggest filing a ticket.

That's what I get - 1 book, when I know I have many.

I'm going to be semi immobile for the next few weeks. This sounds like a simple project to tackle if no one else does it first.

You could create a Catalog for all books, in CSV format. Then sort the CSV file on the "Cover" column. Those books without a cover will have this field blank and so will all be sorted together.

Thanks, but I have other SQL methods to get a list. What I really need, however, is to see them in the GUI so I can tell it to get metadata for all books that have no cover and do not have the tag "Done." That tag signals that I dealt with this book and no cover is available.

Sounds like a bug, if no one else wants to tackle it, file a ticket and I'll take a look.

I finally got a chance to track this down and found the bug today. It looks like it affected all false searches, not just cover:false. It will be fixed in the next release.

The combo of true/false searches and the new regex searches lets me find anything I want. I just had it find all books with an author's last name that starts with L and where there are no tags, ratings or covers, then sent them off to have metadata automatically picked up.
