• The words AND, OR and NOT may confuse the search; try adding quotes: "fop (petr OR ((petru OR peteru) OR (petriou OR (petrov OR (petrioiov OR peteriov))))) _. s.~".
• Adding a wildcard symbol may retrieve word variants: fop (petr OR ((petru OR peteru) OR (petriou OR (petrov OR (petrioiov OR peteriov))))) _. s.*.
