Can't tell if sarcasm; ITA Matrix is one of the most flexible and powerful flight search engines out there.
It's kind of useless to search for the cheapest fares in a whole year, because seat sales are often offered a month or two before the flight, not to mention most airlines only sell seats up to 11 months in advance. Use something like Airfare Watchdog if you want to hear when seat sales happen, then use ITA Matrix to pick dates and routes in the timespan that the seat sale is in effect.
ITA Matrix also has an advanced routing language, which you can use to specify alternate airports, restrict what carriers will be used, what airports to connect through, how many connections to make (both minimum or maximum), what fare codes to use, etc.. I haven't yet found anything else like it on the web; I use it all the time to find flights that will maximize my frequent flyer mileage and minimize my cost.
