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