If your iPhone still says Optimizing Search and Siri, open Settings and note the percentage if one appears. Check it again after leaving the phone idle on a charger and Wi-Fi. Then try a search for a message or contact you know is on the phone. The progress and search results together help you decide what to check next.
Spotlight builds an index so it can find content such as messages, contacts, notes, and apps. Apple says indexing runs after setup and software updates, and it can take hours or days depending on how much data is on the phone. On November 6, one owner reported that a new iPhone still showed 35% after three days, despite leaving it on a charger overnight. See Apple’s Spotlight indexing guide and the MacRumors discussion.
Check the indexing progress
- Open Settings. Look near the top of the main Settings screen for Optimizing Search and Siri. Write down the percentage and time if a progress figure is visible. See an example of the message in iOS 27 Settings.
- Give the phone idle time. Leave it connected to a charger and Wi-Fi while you’re away from it, such as overnight. Apple says indexing goes faster when the device is idle and connected to power and the network.
- Check again later. Open Settings again and note whether the percentage moved or the notice cleared. If it stays at the same value, check whether Spotlight can find content you know is there.
Compare Spotlight with search inside an app
- Pick an item you can see. Open Messages and choose a word from a message in a conversation. Or pick a contact you can see in Contacts. Search for it inside that app first.
- Search for the same item in Spotlight. Swipe down from the middle of the Home Screen and enter the same word or name. Tap Show More if the results are shortened.
- Try a second app. If Spotlight misses the first item, repeat the comparison with an item from another app. Note which apps are affected.
Apple explains how to open Spotlight, expand its results, and search directly in an app in its Spotlight search guide.
| What you see | What to do next |
|---|---|
| The percentage has moved and you can find your test items. | Give the iPhone more idle time on power and Wi-Fi if the message is still visible. |
| You can find an item in its app, but Spotlight misses results from that app. | Check that app’s Show Content in Search setting. Try the same search again. |
| The item is also missing inside Messages, Contacts, or the original app. | Check that app’s account and sync status. After setup, content may still be downloading. |
| The percentage stays the same across checks and Spotlight misses known items from several apps. | Check for an iOS update. If the pattern continues, record the percentage and your test results for Apple Support. |
Check search settings for an app that’s missing
Open Settings → Search and select the affected app. Check Show Content in Search if items from the app are missing, or Show App in Search if the app itself is missing. Enable the option if you want those results to appear, then try the same search. These settings also affect which app content Siri AI can find. See Apple’s per-app search settings.
If several apps still have missing search results
Apple recommends checking for the latest software when Spotlight returns unexpected results. Open Settings → General → Software Update to see what’s available. For the full update steps, see Apple’s update instructions and our guide to updating iOS on an iPhone.
If indexing keeps showing the same percentage and Spotlight still misses items you can find inside several apps, contact Apple Support. Include your iPhone model, iOS version, when you set up or updated the phone, and the percentage and time of each check. Note which apps and searches you tested.
FAQs
How long does Optimizing Search and Siri take?
Apple says a full index can take hours or days depending on the amount of data. Check whether the percentage advances and whether Spotlight can find your test items.
Can I use my iPhone while it’s optimizing?
Yes. Use it as usual. When you have a longer break, leave it idle on power and Wi-Fi to give indexing more time.
What if I need to find a message now?
Open Messages and try searching there. If you can open the conversation, look for the item directly. Comparing the app and Spotlight results also helps narrow down what to check.
Do I need Siri AI to use Spotlight?
You can open Spotlight from the Home Screen and search for apps or contacts. If you’re looking for a separate Siri AI feature, see our guide to checking Apple Intelligence compatibility and settings.
