Fix Search in Settings Not Working on iOS 12

If the search bar inside the Settings app on iOS 12 is unresponsive, shows no results, or crashes when you type, the fix usually involves restarting the Settings app, checking Spotlight Search settings, or resetting the keyboard dictionary. This guide walks through the most effective troubleshooting steps in order, from quick resets to deeper system adjustments.

Why Search in Settings Fails on iOS 12

The Settings search feature relies on a system-wide index maintained by Spotlight. When you type in the Settings search bar, iOS looks through that index for matching preference panes, app names, and settings labels. On iOS 12, several issues can break this:

• Corrupted Spotlight index – The database that powers search can become stale or damaged after an update or restore.
• Keyboard glitches – A stuck QuickType bar or a third-party keyboard can interfere with text input.
• Low storage – iOS may disable background indexing when the device is nearly full.
• Software bugs – Early iOS 12 builds had known search quirks that were patched in later updates.

Because Settings search is tied to Spotlight, fixing it often means refreshing that index rather than just toggling a switch.

Quick Fixes to Try First

Start with these simple actions—they resolve a surprising number of cases:

1. Force-close Settings – Swipe up from the bottom (or double-click Home on older devices) to open the app switcher, then swipe the Settings card away. Reopen Settings and try search again.
2. Restart your iPhone or iPad – Hold the side/top button and either volume button until the power off slider appears. Slide to power off, wait 30 seconds, then turn it back on.
3. Switch keyboards – If you use a third-party keyboard, switch back to the default Apple keyboard in Settings > General > Keyboard > Keyboards. Try search again.
4. Check for a software update – Go to Settings > General > Software Update. If iOS 12.x is available (like 12.5.7), install it—Apple fixed several search-related bugs in point releases.

If none of these help, move on to the more targeted fixes below.

Reset Spotlight Search Permissions

Spotlight can be disabled for individual apps, but the Settings app itself should always be included. Still, a glitch can remove it. To reset:

1. Open Settings > Siri & Search.
2. Scroll down and tap Settings (the app itself).
3. Toggle Search & Siri Suggestions off, wait a few seconds, then toggle it back on.
4. Exit Settings completely and reopen it. Try search.

This forces iOS to re-register the Settings app with the search index. If that doesn’t work, also check Settings > General > Spotlight Search and make sure the toggle for Settings is green.

Rebuild the Search Index

When the index itself is corrupted, the most reliable fix is to force iOS to rebuild it. There’s no direct “rebuild” button, but you can trigger it by:

• Turning off all Spotlight suggestions – Go to Settings > Siri & Search, and turn off every toggle under “Suggestions while searching.” Then restart the device. After reboot, turn them back on. This often forces a re-index.
• Resetting the keyboard dictionary – Go to Settings > General > Reset > Reset Keyboard Dictionary. This clears learned words and can resolve input lag that makes search seem broken.
• Resetting all settings – Settings > General > Reset > Reset All Settings. This doesn’t erase your data, but it resets Wi-Fi passwords, wallpapers, and notification preferences. It also rebuilds the search index. You’ll need to re-enter Wi-Fi passwords afterward.

If you’re comfortable with a full restore, backing up and restoring via iTunes or Finder is the most thorough fix, but try the less disruptive options first.

Free Up Storage Space

iOS 12 can struggle with background tasks like indexing when storage is critically low. Check available space:

1. Go to Settings > General &strong> > iPhone Storage.
2. If the bar at the top shows less than 1–2 GB free, offload unused apps or delete large videos.
3. After freeing space, restart the device and try search again.

Apple’s support documents note that low storage can cause Spotlight to stop updating. This is a common cause on 16 GB devices running iOS 12.

When to Restore the Device

If you’ve tried all the above and search still fails, a full restore is the next step. Before doing this, back up to iCloud or a computer. Then:

1. Connect your device to a computer and open iTunes (or Finder on macOS Catalina or later).
2. Select your device and choose Restore. This reinstalls iOS 12 and rebuilds everything from scratch.
3. After the restore, set up as new or restore from your backup. If you restore from a backup, the issue may return if the backup contains the corrupted index—so test search before restoring data.

Only do this if you’ve exhausted other options, as it takes time and requires a stable connection.

Frequently Asked Questions

Why does Settings search show “No Results” for every query?

This usually means the Spotlight index is empty or corrupted. Try toggling Siri & Search for the Settings app, then restart. If that fails, Reset All Settings is the next best step.

Will resetting all settings delete my photos or apps?

No. Reset All Settings only resets system preferences like Wi-Fi passwords, wallpaper, and notification settings. Your photos, messages, and installed apps remain intact. However, you will need to re-enter Wi-Fi passwords and re-pair Bluetooth devices.

Does this happen on newer iOS versions too?

Yes, search glitches can occur on any iOS version, but iOS 12 is older and less optimized for newer hardware. The same troubleshooting steps generally apply to iOS 13–17, though Apple has improved indexing reliability over time.

Can a third-party keyboard cause Settings search to fail?

Yes. If a third-party keyboard is crashing or not loading properly, the search field may not receive text input. Switch back to the default Apple keyboard and test. You can also delete the third-party keyboard entirely.

Is there a way to search settings without the search bar?

You can manually navigate through the Settings app, but that’s tedious. Alternatively, use Spotlight search from the home screen (swipe down on the home screen) and type the setting name—it often shows the same results as the in-app search.
