If you hit it in the area you said you did, more than likely you have a dead deer waiting to be found.
Don't allow yourself to become impatient so easily and give up too soon, a 10 + point Buck deserves as much tracking effort as possible,
keep this in mind it will be easier finding this dead one (because he isn't going anywhere) vs. trying to harvest another live one.
A gut/liver hit isnt ideal for tracking but it is a kill shot, the deer will be jumpy and heading in no specific direction which means he could end up anywhere,
he may go left for awhile and then turn to go right for no reason and then after 40 or 50 yards turn to head back left again, he's wounded and confused.
Wounded deer try to head for water that's another thing you might want to keep in mind.
Good Luck and let us know if you find him, i'd love to see his pics.
