Apple Mail’s search has been broken for years, and everyone knows it. But iOS 27 should fix that.
When it arrives later this year, it will bring a completely rebuilt Mail search with features such as a new on-device index, relevance ranking and the ability to reindex old emails. The emails you know exist but can never find? Your iPhone will finally be able to surface them.
What’s changing with iOS 27’s Mail search?
Apple acknowledged the inconsistent search results that regularly flummox iPhone and Mac users as they look for an elusive file on their devices. To fix the longstanding problem, the company said it completely revamped on-device search for this year’s operating system upgrades.
“We’ve all had that moment where you search for something you know is there, but it just won’t show up,” said Stacey Ford, Apple’s vice president of OS program management, during Monday’s WWDC26 keynote. “So on iOS, iPadOS and macOS, we’ve rebuilt the foundation of search that powers Spotlight, Photos and Mail.”
With iOS 27, Apple will introduce a persistent, device-side catalog that will give Mail insights into your inbox. This will replace the incomplete local cache the app relied on for so many years.
An updated search index for Spotlight, Mail and Photos
Ford said an updated search index, the “rich catalog your device builds of all your content so it can understand what you have and where to find it,” will power the improved search results in Mail, Spotlight and Photos.
“We rearchitected the index so it’s more stable, more efficient, and more comprehensive of content, both old and new,” she said.
Plus, the Mail app’s new ranking system will reward relevance over recency. Apple says its goal is to bring “the most relevant results to the top to help you find what you need right away — even if it’s buried deep in your inbox.”
In iOS 27, when you open Mail search, you’ll see a banner labeled “Expanded Search Results.” This is the app’s way of indicating that it will now search by intent rather than just relying on keywords. For example, if you search for “dentist,” it should show an email from your dental clinic even if the word did not appear in the mail.
What devices will the new Spotlight and Mail search work on?
Will the Mail app’s improved search features come to all iPhones, Macs and iPads? Your device will need to be capable of running this year’s new operating systems. But it doesn’t look like it will require hardware that supports all the new Apple Intelligence features.
Apple released the first developer betas of its new operating systems this week. iOS 27 should launch this September alongside the iPhone 18 Pro and the rumored folding iPhone. If you want to try them out now, you can download the iOS 27 beta.
