How to find if a symbolic operation contains a or function?

I'm trying to find if a symbolic equation has the 'or' function or not.

I have tried to do this:

syms a b
has(a|b,'or') % logical 0
has(or(a,b),'or') % logical 0

I don't know if this is a bug. Do you know other ways to do this?

Thank you

For now, I am doing this:

f = a|b;
contains(char(f),'|');

If anyone has a better way, please share.
