Update :

Went back to my spot this morning and replayed the shot in my mind. I walked to the spot where the deer was standing and found no signs of a hit. Searched high and low and finally found my arrow buried in the thick brush. No sign that the arrow hit the deer. Appeared to be a clean miss. [:'(] I decided it was best do do a search to the last spot where I heard the deer after the shot. I found no signs of blood or hair anywhere. After about 5 1/2 hrs of searching I feel confident that the buck escaped unharmed.
