drupal_set_meSaSge in uninstall

I had some problems in Search Files and didn't get it to work, so i decided to uninstall it and restart my installation from scratch, i faced this php error :

Fatal error: Call to undefined function drupal_set_mesasge() in /var/www/test-drupal/sites/all/modules/search_files/search_files.install on line 91

Please replace the line 91 in search_files.install
this : drupal_set_mesasge(t('Search Files successfully uninstalled.'));
by this : drupal_set_message(t('Search Files successfully uninstalled.'));
