Summary

This guide helps you troubleshoot and resolve: How to fix and reset the Windows 11 Windows Search indexer when File Explorer search returns no results or is extremely slow. Follow the steps below to fix the issue.

Common Causes

When the Windows 11 search index becomes corrupted or outdated, File Explorer search may return no results, display incomplete results, or become painfully slow. Rebuilding the index forces Windows to rescan your files, folders, and apps from scratch, which typically restores fast and accurate search results. This guide walks you through the steps to repair and reset the search index on Windows 11.

Quick Fix Steps

1. Press Windows + R, type services.msc, and press Enter.
2. Locate Windows Search in the list, right-click it, and select Restart.
3. Restart your computer and test File Explorer search.

If the quick fix does not resolve the issue, proceed to the detailed instructions below to fully rebuild the search index.

Detailed Instructions

Method 1: Run the Search and Indexing Troubleshooter

1. Open Settings > System > Troubleshoot > Other troubleshooters.
2. Locate Search and Indexing and click Run.
3. Follow the on-screen prompts and select the issues you are experiencing.
4. Apply any recommended fixes and restart your computer.

Method 2: Rebuild the Search Index from Settings

1. Press Windows + I to open Settings.
2. Navigate to Privacy & security in the left pane, then select Searching Windows.
3. Scroll down to the Indexing status section.
4. Click the Advanced indexing options link. This opens the classic Indexing Options control panel window.
5. In the Indexing Options window, click Advanced at the bottom.
6. In the Advanced dialog box, click Rebuild under the Troubleshooting section.
7. Click OK to confirm. Windows will warn you that rebuilding can take a long time on large drives.
8. Click OK again to start the rebuild process.
9. Close all windows and restart your computer.

Method 3: Restart the Windows Search Service

If rebuilding the index does not work, the underlying Windows Search service may be stuck or unresponsive. Restarting it can resolve persistent issues.

1. Press Windows + R, type services.msc, and press Enter.
2. Scroll down and locate Windows Search in the list.
3. Right-click Windows Search and select Restart.
4. If the service is stopped, right-click and select Start.
5. Confirm the Startup type is set to Automatic (Delayed Start).
6. Close the Services window and test File Explorer search again.

Method 4: Verify Indexed Locations

Search will only return results from locations that have been added to the index. If your files are stored in a non-indexed location, they will not appear in search results.

1. Open Settings > Privacy & security > Searching Windows.
2. Click Advanced indexing options.
3. In the Indexing Options window, click Modify.
4. Review the list of indexed locations under Change selected locations.
5. Expand each drive and folder to verify that the locations containing your files are checked.
6. Check any missing locations you want to include, then click OK.
7. Click Close to finish.

Method 5: Check File Explorer Folder Options

Sometimes search issues are caused by File Explorer settings rather than the index itself.

1. Open File Explorer by pressing Windows + E.
2. Click the ... (three dots) menu in the command bar and select Options.
3. In the Folder Options dialog, switch to the Search tab.
4. Under What to search, select Always search file names and contents.
5. Click Apply, then OK.

Troubleshooting

Search Still Returns No Results After Rebuilding

• Confirm the Windows Search service is set to Automatic (Delayed Start) in services.msc.
• Check for pending Windows updates in Settings > Windows Update and install any available updates. See our guide on How to update Windows.
• Verify that your user profile has read permissions on the folders you are searching.
• Try toggling the Find my files setting between Enhanced and Classic under Settings > Privacy & security > Searching Windows, then restart.

Search Is Slow Even After Rebuilding

• Reduce the number of indexed locations by excluding folders you do not need to search, such as large media libraries or backup drives.
• Exclude common system folders from the index if they are not needed for search.
• Check disk health using wmic diskdrive get status in an elevated Command Prompt. A failing drive can dramatically slow indexing.
• Consider whether your machine meets the recommended specifications for Windows 11. See Optimising Windows 11 Performance for further guidance.

Indexing Never Completes

• Open Indexing Options and check the Indexing status to see how many items remain.
• Temporarily disconnect any external or network drives, as these can stall the indexing process.
• Disable your antivirus temporarily to rule out interference, then re-enable it once indexing completes.
• Ensure your system drive has at least 10% free space. Low disk space can prevent the index from completing.
