title: How to add google chrome omnibox-search support for your site?
body: <p>When I enter some of URLs in Google Chrome omnibox, I see message in it "Press TAB to search in $URL". For example, there are some russian sites habrahabr.ru or yandex.ru. When you press TAB you'll be able to search in that site, not in your search engine.
  How to make my site to be able for it? Maybe, I need to write some special code in my site pages?</p>
