  * To add to Chrome, go to Settings > Search [Manage search engines...] > Other search engines.
  *   At the bottom of this section, there are three required fields:
  *     [Add a new search engine] [Keyword] [URL with %s in place of query]
  *     - Add a new search engine: Descriptive name of your search
  *     - Keyword: used to trigger search.
  *         Example: typing maps.google.com then hitting [tab] or [space] replaces the search bar with a Google Maps search.
