Google search does not work!

Hi, I am having a problem on Google Chrome that the search box does not work correctly. When I search something on the Google search box, it does not work. Can anyone please suggest what to do? How can I able to solve the issue?

After not getting any response, I shared the issue with one of my friends and he sent me this article. I followed some useful methods from there. First I disabled the Chrome extension and then cleared the browser cache. After completing the tasks properly when I searched something on Google, it was working fine.
