Bing (search engine) effort to better compete in the market. The first public beta of Windows Live Search was unveiled on March 8, 2006, with the final release on September 11, 2006 replacing MSN Search. The new search engine used search tabs that include Web, news, images, music, desktop, local, and Microsoft Encarta. In the roll-over from MSN Search to Windows Live Search, Microsoft stopped using Picsearch as their image search provider and started performing their own image search, fueled by their own internal image search algorithms. On March 21, 2007, Microsoft announced that it would separate its search developments from the Windows
Microsoft Search Server to extract the text of the file for full text indexing as well. The handlers and iFilters MSS uses are the same as used by SharePoint, Microsoft SQL Server and Windows Search as well. The data sources that are to be indexed are identified by their URIs and have to be configured prior to indexing. The indexer updates the search index as soon as an item is indexed ("continuous propagation") so that the items can be queried against even before the indexing crawl is complete. MSS can also federate searches to other search services (including SharePoint and web search servers)
