Summary: Learn how to reset the SharePoint search index.

When you reset the search index, all content is immediately removed from the search index and users will not be able to retrieve search results. After you reset the search index, you must perform a full crawl of one or more content sources to create a new search index. Users will be able to retrieve search results again when the full crawl is finished and the new search index is created.

NoteNote:
After a search index reset, a full crawl won't restore all analytics features that are powered by the Analytics Processing Component. Examples of analytics features are raising or demoting items in search results based on which search results users have clicked, or displaying the number of times a search result has been viewed. For more information, see Overview of analytics processing in SharePoint Server 2013.
If you can, you should perform a backup and restore of your Search service application instead of a search index reset. These procedures will fully restore all features that are powered by the Analytics Processing Component. For more information, see Back up Search service applications in SharePoint 2013 and Restore Search service applications in SharePoint 2013.

NoteNote:
Because SharePoint 2013 runs as websites in Internet Information Services (IIS), administrators and users depend on the accessibility features that browsers provide. SharePoint 2013 supports the accessibility features of supported browsers. For more information, see the following resources:

Before you begin this operation, review the following information about prerequisites:

  • Create a Search service application.

  • Add one or more content sources.

  • Perform at least one full crawl.

  • Make sure that you are not running a backup of the Search service application when you reset the search index.

Use the following procedure to reset the search index.

To reset the search index
  1. Verify that the user account that is performing this procedure is an administrator for the Search service application for which you want to reset the search index.

  2. On the SharePoint Central Administration home page, in the Application Management section, click Manage service applications.

  3. On the Manage Search Applications page, click the Search service application for which you want to reset the search index.

  4. On the Search Administration page, under System Status, verify that the Administrative status of the Search service application is Running and not Paused.

  5. On the Search Administration page, in the Crawling section, click Index Reset.

  6. On the Index Reset page, verify that the Deactivate search alerts during reset check box is checked, and then click Reset Now.

  7. In the confirmation dialog box that appears, click OK to confirm that you want to reset the index.

    The Search Administration page opens and the System Status is displayed.

After the search index reset is complete, you must perform a full crawl of all the content sources that you want to include in the search index. For more information, see Add, edit, or delete a content source in SharePoint Server 2013. Users will not be able to retrieve search results until you create a new search index.

After the full crawl has completed and a new search index has been created, you must also re-enable search alerts. See Enable search alerts in SharePoint Server 2013.
