Federico Viticci has a comprehensive write-up about Apple’s approach to search in iOS 9, including comments from developers. On local app search:
“With local app search, iOS 9 can build an index of content, app features, and activities that users may want to get back to with a search query. Built like a database and already in use by Apple apps such as Mail and Reminders, CoreSpotlight will provide low level access to the index of an iOS device, making it easy to organize and retrieve content users have previously seen, created, or curated.”
I’ve been slowly going through WWDC session videos, but haven’t cracked open the documentation for search yet. Sounds like an important new API for any app that has user documents.
