Will we be able to take advantage of the Spotlight search within our own apps? Or only where they have provided the search boxes for us?
EDIT: to clarify, I'm not looking to search data within my app, but search things like mail from my app.
In searching for the answer, I saw a lot of the same announcements that don't give any detail. Some mention a Spotlight API, but almost make it seem like it is just a way to tag our apps to be found by the searches instead of actaully being able to execute a search.
