"Nothing to repeat" is a regex error - the initial question mark is
not escaped, so Python thinks you are trying to use it as a wildcard.
In fact, you are going about this the wrong way. Query parameters -
those after the ? in a URL - are not dealt with in the URLconf at all,
but are passed in the request.GET dictionary. So you your urlconf
should be:
(r'^$', 'businessnamesearch_view')
and the view should be:
def businessnamesearch_view(request):
business_name = request.GET.get('business')
...etc...
