 A context type that represents a simple search criterion, based on a list of other context objects, that can be used to search or filter content in an application (such as messages in a chat app).
+No implementation details of how to apply the search criteria are specified. It is up to the application that receives the intent to define how it handles the criteria. (Example: apply an OR between each criterion, etc...)
