Try the website skyscanner.com, really good and fine. There you should find a flight for you even if there would be a stop over. For example, I booked my flight on the 29th July from Venice to Copenhagen then from Copenhagen to Dublin with SAS... And for the return from Dublin to Frankfurt and then Frankfurt to Venice with Lufthansa!
