After a major iOS, iPadOS, or macOS update, it's quite common to notice that Spotlight finds fewer things, takes too long to show results, or simply doesn't seem to work properly.This doesn't necessarily mean the update has broken anything. Apple has published a new support document explaining what's happening: Spotlight needs to recreate and update a local index with the content on our device. This includes documents, messages, contacts, photos, notes, emails, apps, and settings. Siri can also use part of this index to respond to our requests. And here's the important detail: if we have a lot of data, completing the process can take some time. several hours and even days.
Getting it to finish faster is quite simple. Apple recommends Leave the device unused, plug it into a power outlet, and keep it connected to the internet via Wi-Fi or Ethernet.This last point is especially important when the system needs to download emails or other data before adding them to the index. In my case, I would do exactly the same as after restoring an iPhone: leave it overnight connected to the charger and a good Wi-Fi network before looking for more aggressive solutions. On the Mac, we can check if Spotlight is still working by pressing Command + space barIf indexing is active, a progress indicator will appear at the top of the window. On iPhone and iPad, you may find a notification in Settings indicating that... Search and Siri are being optimizedWhile Mail may display its own warning if it hasn't finished indexing the email, Apple also clarifies something we sometimes forget: the index is local and private, remaining on each device and not shared with Apple or our other devices. Therefore, an iPhone, an iPad, and a Mac will have to complete the process separately.
If after several days Spotlight still can't find certain content, then it's worth checking the settings. iPhone or iPad, go into Settings > Search and check that the apps or content you're missing are enabled to appear in search results. On a Mac, we can go a step further: System Settings > Spotlight > Search PrivacyTemporarily add the problematic folder or drive to the excluded locations, wait a few seconds, and then remove it again. This forces Spotlight to reindex that content. My advice, however, would be to leave everything alone immediately after updating: charging, Wi-Fi, and a few hours of patience are usually a much more sensible solution than blindly rebuilding indexes.
