A adição de um novo mecanismo de pesquisa ao Google por meio do seguinte funcionou para mim:
1) Go to the Chrome Settings page and choose Search > Manage Search Engines
2) Go to add new search option. This might vary depending on what Chrome version you’re on, but you get the gist.
3) Give it a name, it doesn’t really matter what, I use “Go straight to”
4) Give it a shortcut key. This will tell Chrome you want to use the ‘Go straight to’ option. I use backslash “\”. So when you want to use Feeling Lucky, you type “\” followed a space and whatever name or term you want to go straight to.
5) In the third box for the URL, paste http://www.google.com/search?ie=UTF-8&oe=UTF-8&sourceid=navclient&gfns=1&q=%s

Observe que, como alternativa ao passo 1, você pode copiar e colar o seguinte em uma nova guia:
chrome://settings/searchEngines?search=manage
