I hope my thread is right here?
Until version 5.40 I could send a query to show me which authors do not have a comma in the string like "Ludlum, Robert" and is sorted as column author_sort shows them.
The query string used is: " not author = "," " (1)
Also " not authors = "," "
Where as " authors = "," " shows them when including a comma.
The request ends with an empty list. No error message appears.
Since version 5.41 the query doesn't work anymore.
Does anybody know, why it doesn' work?
Configuration:
Latest version of Calibre 64 with 24.000 titles on
Windows 10-Notebook Panasonic FZ-55,
64 GB RAM + 2 TB m.2.
Thank you for reading and constructive help.
