searching for author missing name OR first name (not both)

[whismerhill]

pretty much the title
I'd like to search for when the Author field is half filled:
-e.g. it has name but no first name
-or eventually first name but no name

I found a plugin quality check but it doesn't seem possible with it ?


it all sums up to this :
-search in author field for fields containing only one word & no more.
thanks.

You can search for authors with one-word names like this:

authors:"~^\S+$"

This will at least reduce the amount of stuff to look at (although legitimate single-word-author names like "Anonymous", "Various", "Confucius" and "Saki" will still show up).
