How to find easily books with multiple authors?

wladdy · 04-08-2013, 03:17 PM

Hi,

I need to find in the main interface all books with multiple authors
After reading this article I assumed that I needed to use a regular expression to find all books with "&" in the author field. Unfortunately, the following search return nothing:

author:~\&

I'd very much appreciate if someone could explain what I am doing wrong and point me in the right direction.

On the same topic, I would appreciate advice to find all books with one single author or no author at all.

Thanks in advance. W.

& is a flag, the real link is (hidden in the DB ) author numbers, which is why it will not work.

Try
authors:#>1

That works great.
I have a column with a formula in it which I can delete now.

You can search for ampersand in author_sort, there it works as intended. But authors:#>1 is better.

Perfect! I had the same problem.

You can ignore my tweet then.
