@
gianni_1 - the regular expression field is irrelevant if the
Read metadata from file contents rather than file name option is checked. When that option is checked the metadata (author, title, publisher, publication date etc) that is embedded in the book will be used.
If you rename the file to:
Code:
Tex Willer. L'ouragano - Numero 129.pdf
and set the regex to:
Code:
(?P<title>[^_]+) - (?P<author>.+)
you should get what you want.
