• The words AND, OR and NOT may confuse the search; try adding quotes: "fop (petr OR (((petriu OR petriiu) OR petriiu) OR (petroou OR (petrov OR petruiov)))) _. s.~".
• Adding a wildcard symbol may retrieve word variants: fop (petr OR (((petriu OR petriiu) OR petriiu) OR (petroou OR (petrov OR petruiov)))) _. s.*.
