Open Finder.

Click Go in the top menu bar, hold down the Option key, and click the hidden Library folder that appears.

Navigate to Application Support > com.apple.sharedfilelist.

Delete the file named com.apple.LSSharedFileList.ApplicationRecentDocuments.sfl3 (or any similar .sfl database files).

In the "Terminal" app type:

sudo mdutil -E /

press Enter

Note: Reindex may take a while depending on the amount of files on the drive.
