Fix Surname Name to -> Name Surname without , to recognize

Hi there!

I have some books that have the author name swaped. And there is no comma between, so its not easy to find.

I thought about searching if there is a reverse result.
Something like the duplicates finder.

Group the author name to one group and surname to another group and search if there is a result in surname name.

But I dont now how to realise this in Calibre.

Thanks for your helps! :thanks:
