Over past few years Google Search is improved a lot, from starting Image search, Blog search to suggesting Search Keywords to user.
I can see one more addition to Keyword suggestion feature, which shows a direct link in suggest box for first possible url of search keyword following with suggested keyword and then ‘Search’ and ‘I am feeling lucky’ buttons at the top of it, this is useful for those who use Search button click to search phrases.
I found nice article on C# Orcas new features.
