At Ignite 2018, officials said publicly that Microsoft's plan was to put the search box "in a consistent, prominent place across Edge, Bing, Windows and Office apps, so that search is always one click away." The company also would be "supercharging" the search box so that users can more easily find people, related content, commands for apps and more before they actually start typing in the search box, as it will be contextually aware and offer proactive search results and suggestions.
A week ago, I asked Microsoft if the company was still planning to bring Microsoft Search to Windows 10, as no one seemed to be talking about this any more. Microsoft has a new blog all about the Windows Search platform, but the Windows Search platform is not the same as the Microsoft Search platform. And Microsoft is continuing to add new functionality to the Windows Search platform, not the Microsoft Search platform, in new test builds of Windows 10.
Microsoft's description of this feature on the roadmap: "We're bringing Microsoft Search to the Windows 10 search box. Microsoft Search is an enterprise search experience that increases productivity and saves time by delivering more relevant search results for your organization."
it's a combination of the Microsoft Graph, the company's centralized application programming interface, plus semantic knowledge from Bing, that Microsoft execs have said will make this more personalized and unified search experience work. The Microsoft Graph is what contributes an understanding of users' work life, meaning the documents, the entities, the people they work with regularly and other everyday signals. Bing contributes an understanding of the world outside an organization, with acronym and entity extraction, machine reading comprehension and computer vision.
