It was indeed not working, because of the database table collation for the cyrillic symbols. I have changed the code to I have suggested to:
$this->parts = array( array("( $wpdb->posts.ID LIKE '$s' )"), array() );
Now it should search IDs and terms correctly if your switch back to the regular engine along with the ID exclusions.
The demo was indeed not working because there was a maintenance on one of our database servers 🙂
