TechCrunch:
Apple is switching the default provider of its web searches from Siri, Search inside iOS (formerly called Spotlight) and Spotlight on the Mac. So, for instance, if Siri falls back to a web search on iOS when you ask it a question, you’re now going to get Google results instead of Bing.
“Switching to Google as the web search provider for Siri, Search within iOS and Spotlight on Mac will allow these services to have a consistent web search experience with the default in Safari,” reads an Apple statement sent this morning. “We have strong relationships with Google and Microsoft and remain committed to delivering the best user experience possible.”
This will change on iOS for the ‘I don’t know what you’re asking but here are web results’ Siri behavior as well as intentional ‘hey, Siri, search the web for…’ queries.
I don’t know if average users even notice what service is providing them with search results. Where I can, I’ve switched to DuckDuckGo for my searches.
