The start screen search (the default Windows 8 search) will not find an application until the entire first word of the application is entered. This is inconvenient, especially if I can't remember the exact name of the application. When I change to 'classic' start menu style I can just press the window key and type in three letters which will immediately present all applications with those three letters even if not the first three characters of the application name. Why would this search work so much better than the default, and is there a way to make the default search work the same way?
This is the normal (rubbish) behavior of Windows 8 search. The 'classic' view and better search capability is provided by 'Classic Shell' 3rd party app, which I (and many others) recommend.
