Using Google (or any other) search, is there a way to find out the number of websites that have included a particular javascript file? Like, for example, if I want to find out the approximate number of pages that have included http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js, then can I do this using Google (or Yahoo!, or Bing, or whatever)?
EDIT :
I think I may have stated my question wrong. I am interested in finding out those web pages that have included the script in their <head>, like: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>.

"jquery/1.7.1/jquery.min.js"or"http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"? – Computist Jan 19 at 7:33<head>, like:<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>– Saadat Jan 19 at 7:42
