It is the system search I was describing. Actually the OS itself doesn't
search at all; rather it asks all the apps (if the are registered as
supporting search) to perform a search within their own data, be it
organized in soups or whatever. The OS doesn't have to care about how
data is stored within an app. A system-wide search is just multiple app-
based searches combined into one; the OS only supplies a unified
interface for initiating searches and showing the results, but not the
search algorithms. If an app doesn't support search (i.e. Find or
DateFind), its data will never show up in searches. But if the developer
DOES implement Find or DateFind, the app will support global find even
when it stores its data in some never dreamt of innovative way. It might
even perform some ad hoc calculations to create the requested data,
rather than retrieving already existing data from a soup. This is
extremely flexible.
