Perhaps you should try some spelling variations:
"fop peruov OR petri OR per OR peterio OR peterio OR peterio OR petr o.s.*" » "fop peruov OR peteri OR per OR peterio OR peterio OR peterio OR peter o.s.*" (Expand Search), "fop peruov OR petrui OR per OR peterio OR peterio OR peterio OR petru o.s.*" (Expand Search), "fop peruov OR petroi OR per OR peterio OR peterio OR peterio 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 (peruov OR (((petri OR per) OR ((peterio OR peterio) OR peterio)) OR petr)) o.s.*.
