• The words AND, OR and NOT may confuse the search; try adding quotes: "fop (petr OR ((petrui OR petriu) OR ((petrooou OR petrooou) OR (peterov OR petrov)))) _. s.~".
• Adding a wildcard symbol may retrieve word variants: fop (petr OR ((petrui OR petriu) OR ((petrooou OR petrooou) OR (peterov OR petrov)))) _. s.*.
