Google Search Result Crawling Not working

I have tried using class id "g" , "r" and "rc" for obtaining google search results with no luck. Please help. I was not able to accomplish this on the demo blog either but thought maybe it was a glitch that would be fixed when I installed it on my website.   I followed the guide here to no avail: https://www.youtube.com/watch?v=l9sUu8rcwoc&ab_channel=CodeRevolutionTV   Thank you for the help
