    # rm -rf /usr/local/psa/var/modules/catalog/search/*

  3. Reinstall Plesk Extension Catalog:

    # plesk bin extension -i catalog

  4. Recreate the indexes:

    # plesk daily SearchIndex

For Plesk on Windows:

  2. Delete all files in folders %plesk_dir%varsearch and %plesk_dir%varmodulescatalogsearch.
