• The words AND, OR and NOT may confuse the search; try adding quotes: "fop (((peterw OR ((petr OR per) OR petri)) o) OR (((petru OR petriu) OR (petruv OR petrv)) _)). s.~".
• Adding a wildcard symbol may retrieve word variants: fop (((peterw OR ((petr OR per) OR petri)) o) OR (((petru OR petriu) OR (petruv OR petrv)) _)). s.*.
