How to Rebuild Search Index in Windows 11

When the Windows 11 search bar stops working correctly, displays incomplete results, or fails to find existing files, a corrupted search index database is often the root cause. Rebuilding the index wipes the current database and recreates a fresh catalog of all designated files, folders, and applications. This guide provides clear, step-by-step instructions to rebuild the Windows Search indexing database and restore normal search functionality in Windows 11.

Step 1: Open Indexing Options

1. Press Windows Key + I to open the Settings app.
2. In the left sidebar, click on Privacy & security.
3. In the right pane, scroll down and select Searching Windows.
4. Scroll to the bottom of the page and click on Advanced indexing options to open the classic Indexing Options control panel.

Step 2: Access Advanced Settings

1. In the Indexing Options window, ensure your user account has administrative privileges.
2. Click the Advanced button located near the bottom of the window.
3. If prompted by User Account Control (UAC), click Yes to continue.

Step 3: Rebuild the Search Index

1. In the Advanced Options window, locate the Index Settings tab.
2. Under the Troubleshooting section, click the Rebuild button.
3. A confirmation dialog will appear, warning you that rebuilding the index may take a long time and search results might be incomplete until the process finishes. Click OK to confirm.

Step 4: Wait for the Indexing Process to Finish

The system will now delete the old database and scan all specified locations to create a new index.

• The status at the top of the Indexing Options window will change to “Indexing speed is reduced due to user activity” or show a counter of indexed items.
• When the process is complete, the status will state Indexing complete.
• You can close the Indexing Options window while the process runs in the background.

Alternative: Run the Search and Indexing Troubleshooter

If rebuilding the database does not resolve the issue, you can run the built-in troubleshooter:

1. Open Settings (Windows Key + I).
2. Navigate to System > Troubleshoot > Other troubleshooters.
3. Find Search and Indexing and click the Run button next to it.
4. Select the issues you are experiencing (such as “Can’t start a search or see results”) and follow the on-screen prompts to apply automated fixes.
