Когда я запускаю эту функцию, я получаю:

Invalid http://ajax.googleapis.com/ajax/services/search/web
Но тот же запрос в Google возвращает результаты, даже если сгенерированный запрос, находящийся в адресной строке браузера, возвращает действительные результаты

Но я не могу получить никаких результатов. Может кто-нибудь помочь и объяснить, что я делаю не так?
