Perhaps you should try some spelling variations:
"fop petriov OR petri OR pero OR petero OR petrou OR peteru OR petruo OR petr o.s.*" » "fop peteriov OR peteri OR pero OR petero OR peterou OR peteru OR peteruo OR peter o.s.*" (Expand Search), "fop petruiov OR petrui OR pero OR petero OR petruou OR peteru OR petruuo OR petru o.s.*" (Expand Search), "fop petroiov OR petroi OR pero OR petero OR petroou OR peteru OR petrouo OR petro o.s.*" (Expand Search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: fop (petriov OR (((((petri OR pero) OR petero) OR (petrou OR peteru)) OR petruo) OR petr)) o.s.*.
