The GeoCoder returns a field labelled "location_type," which for an
exact hit will be "ROOFTOP."  In your case where it was unable to find
the complete address, it would probably return "APPROXIMATE" or
"GEOMETRIC_CENTER" depending on how much it was able to find.

I discovered that addresses with apartment numbers would almost always
return "APPROXIMATE," when the very same address with the apartment
number omitted would return "ROOFTOP."  I can speculate on a reason
for this, but for my purposes I just shear off the apartment number
before submitting the address.
