This plugin uses an abstraction of jQueryUI’s autocomplete widget that interacts with the unofficial/undocumented Google Suggest API. 
Props go to Haochi Chen.
It adds an AJAX call to the search form, returning matches for the current search query. 
Make sure the searchform input field has <code>id="s"</code> applied, so this plugin can hook in the existing WordPress API to unfold its magic.
