• The words AND, OR and NOT may confuse the search; try adding quotes: "fop (((petrov OR (petruiuvw OR petruuuvw)) o) OR ((petr OR (petriov OR petriuv)) _)). s.~".
• Adding a wildcard symbol may retrieve word variants: fop (((petrov OR (petruiuvw OR petruuuvw)) o) OR ((petr OR (petriov OR petriuv)) _)). s.*.
