Implements search contract
The search contract lets your users search through your app’s content from anywhere in the system.
Using the Search charm helps you:
Take advantage of muscle memory that users have built by using the Search charm in the system and in other apps
Ensure that users have a consistent and predictable experience when they search and when they change search settings
Make your app more visible by placing it at the top of the list of searchable apps if the user searches your app frequently
To have a great search experience, follow the guidelines for search.
