As evident from the name, this charm lets you search anything on your system.
This gives you two panes: The left pane shows search results. The right pane lets you type in your search, as well as select the search scope.
This type is used to search for files, folders and system settings throughout your system.
As described in the above picture, the system-wide search gives results in three different tabs:
The real beauty of Search Charm is its context-sensitive search. It works within the context of your current screen or active app. This search works only in Metro apps, however.
Suppose, you want to search applications related to cooking in Windows Store. Simply summon the search bar, and type “cook”. It will give you the following results.
The search performs a search within the context of Store app, and lists 5 search results.
You can change the search context from within the search pane itself, by selecting the desired Metro app. If the so-selected app hasn’t been launched yet, the system will do it for you and make it ready to be searched within.
The usefulness of context-sensitive search can be seen in Mail app, too. The Mail app would easily become one of the most-used apps. So it needs to have easy-to-use search functionality. The context-sensitive search charm does a very good job here.
The search term “dark knight” (yeah. TDKR fever is everywhere!) gives you two mails that have the “dark knight” in their mail content.
The only (and, perhaps, a deal breaker for many people) constraint is that the context-sensitive works only with Metro apps.
The traditional apps will have to do with the old, slower search wherever available.
So enhance your productivity with the Search Charm next time you want to search/launch/customize anything!
