The Search Charm will receive several improvements in the next Windows upgrade
Windows Blue, the first major Windows 8 refresh that could hit the market as Windows 8.1, is very likely to bring a better search tool, obviously available via the integrated Search Charm.Paul Thurrott of WinSuperSite.com discovered that Windows Blue might search through apps, settings and files by default, without requiring users to manually choose the type of results they want to get.
In Windows 8, whenever a user performs a search, he is provided with three different main sections, namely apps, settings, and files, but also with the installed Metro apps, to better filter the provided results. Blue, on the other hand, will search through all these categories by default, just like the built-in Spotlight tool does on Mac OS X.
The search option is disabled in the leaked build of Blue, so we can’t tell for sure whether this tool could make it to the stable version or not, but it’s clearly a pretty helpful change.
