The search engine "Bing" was known by all these name except?

The search engine Bing was not formerly known as Microsoft Search. Microsoft Search is a separate workplace and enterprise search service, although it has been integrated with Bing in some Microsoft products.

Bing launched in June 2009 as Microsoft’s consumer web search engine. It replaced Live Search, which had previously followed Windows Live Search and MSN Search as Microsoft’s main search brands. Those earlier names represent the service’s direct branding history.

Microsoft promoted Bing as a decision engine, emphasizing features such as visual search, related searches, travel information, shopping tools, maps, news, and multimedia results. The service also became important beyond Microsoft’s own websites when it powered search results for Yahoo under a long-running partnership.

A common source of confusion is the phrase “Microsoft Search in Bing.” That name refers to the combination of Bing’s public web search with an organization’s internal Microsoft 365 information. It does not mean that Microsoft Search was an earlier name for Bing. The direct predecessors were MSN Search, Windows Live Search, and Live Search.
