Thank you for erbanku for sharing. Surprised this isnt top of the gist web page on gist since so useful. The custom search is very useful. Works same in Microsoft Edge as well using settings->Address bar and search ->Mange search engines->Add . You get similar menu as in chrome where you give the custom search engine a name, a keyword for use in browser to invoke this search engine - I used mg as keyword - and URL as you have shown replacing your username with mine
