I am programmatically parsing for results from Google using PHP "simple html dom" library. (Sample URL: "http://www.google.com/search?hl=en&safe=active&tbo=d&site=&source=hp&q=$search") But after a couple of searches, I start getting empty responses totally. Is it due to Google limits? What can be a workaround for this? Any help will be highly appreciated. Thanks
