Searching by Major with '&' in Name

When you search by major and the major's name includes the '&' symbol the system reads after the & as a new field causing a 'Invalid argument supplied for foreach()' error. 
Shortened Ex:
"department=-1&level=grad&grad=Marriage+%26+Family+Therapy&type=internship"
[args] => Array(
[department] => -1
[level] => grad
[grad] => Marriage
[Family_Therapy] =>
[type] => internship)
