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