Related to this: I am trying to remove "Crossover" from fanfics that technically aren't crossovers:

program:
	f = $#fanficcat;
	if 
		contains(
			f, '^Crossover, Mass Effect Trilogy, Mass Effect: Andromeda$', '1', ''
		)
	then 
		'Mass Effect Trilogy, Mass Effect: Andromeda' 
	elif
		contains(
			f, '^Crossover, Half-Life, Portal$', '1', ''
		)	
		then 'Half-Life, Portal' 
	else
		$#fanficcat;
	fi

However, this fails if the tags aren't in that exact order. Since it appears sorted in book details it's hard to tell. Is there a better way to do this?
