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