In my case, I was doing this:
Code:
&& publisher == '(Archive of Our Own|FanFiction.net)'
"that doesn't work, i'll try an in instead," so:
Code:
&& publisher in '(Archive of Our Own|FanFiction.net)'
"that gets the right result but looks backwards, will it work the other way?"
Code:
&& '(Archive of Our Own|FanFiction.net)' in publisher
