Assuming you have properly indexed the corpus for CQPweb (with unique <text_id>) and are using Linux or Mac, you can use a command-line trick:

	A = ".*gerücht.*" %c;
	size A; # number of hits

	set PrettyPrint off; # essential, otherwise you get count + 1
	group A match text_id > "| wc -l"; # number of distinct text IDs

A faster solution that should work everywhere:

	B = A expand to s;
	size B; # number of texts

Best,
Stefan
