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