Site search gets supplemental (Google Custom Search Blog)

This was basically just an announcement from Google about the addition of supplemental search results for Google Custom Search engines.  If your filtering custom search has 3 sites or less, or if includes the entire Internet, you'll start seeing supplement results in you custom search results.

  Watch Out MyBlogLog - Here Comes Explode (TechCrunch)
