Perhaps you should try some spelling variations:
"fop petriov OR petrov OR petriuiu OR petruuuiu OR peteruo OR peteriiuo OR petr o.s.*" » "fop peteriov OR peterov OR peteriuiu OR peteruuuiu OR peteruo OR peteriiuo OR peter o.s.*" (Expand Search), "fop petriiov OR petriov OR petriiuiu OR petriuuuiu OR peteruo OR peteriiuo OR petri o.s.*" (Expand Search), "fop petruiov OR petruov OR petruiuiu OR petruuuuiu OR peteruo OR peteriiuo OR petru 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 petrov) OR ((((petriuiu OR petruuuiu) OR peteruo) OR peteriiuo) OR petr)) o.s.*.
