Or operator in emacs regexp with "Mx occurs"

Question

I wanted to get an overview of my Python program, so I ran:

M-x occur

and for the regex i provided

(def)|(class)

which couldn't match anything.

I also looked at this post and tried

(def)\\|(class)

but that didn't match anything either ...

How do I get M-x occur

for a match class

or def

?

You must use a single backslash (no parentheses, or you must also avoid parentheses):

def\|class
