Introduction:
=============
Bing (formerly Live Search, Windows Live Search, and MSN Search) is a web search engine (advertised as a
decision engine) from Microsoft. Bing was unveiled by Microsoft CEO Steve Ballmer on May 28, 2009 at the
All Things Digital conference in San Diego. It went fully online on June 3, 2009, with a preview version
released on June 1, 2009. Notable changes include the listing of search suggestions as queries are entered
and a list of related searches (called Explore pane) based on semantic technology from Powerset that Microsoft
purchased in 2008. On July 29, 2009, Microsoft and Yahoo! announced a deal in which Bing would power Yahoo! Search.
All Yahoo! Search global customers and partners are expected to have made the transition by early 2012.
In October 2011, Bing announced it is working on new back-end search infrastructure, with the goal of delivering
faster and slightly more relevant search results for users. Known as 揟iger,� the new index-serving technology is
being incorporated into Bing globally starting in August 2011.
