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