IndexingÂ the content of your PC helps you get faster results when your searching it for files, emails, or other local content.
You can choose to useÂ ClassicÂ orÂ EnhancedÂ search indexing mode for where your PC will search for files.
The index uses theÂ Windows SearchÂ serviceÂ and runs as theÂ Searchindexer.exeÂ process in the background. The index will automatically rebuild and update for changes made to the included locations since the last index rebuild to increase search result accuracy.
By default, the searchÂ indexer backoffÂ feature will reduce indexing speed while rebuilding the index when there is user activity, and will automatically continue at full speed when no user activity is detected.
If you are getting search results that are missing, no longer valid, or incorrect, then the search index may not be up to date. You can rebuild the index to force it to update now. You can also reset search index locations to default before rebuilding the search index.
This tutorial will show you how to manually reset and rebuild the search index for accurate search results in Windows 11.
