Perhaps you should try some spelling variations:
"fop petriiv OR petriov OR petruiiov OR petero OR peterov OR petruiiuo OR petr o.s.*" » "fop peteriiv OR peteriov OR peteruiiov OR petero OR peterov OR peteruiiuo OR peter o.s.*" (Expand Search), "fop petriiiv OR petriiov OR petriuiiov OR petero OR peterov OR petriuiiuo OR petri o.s.*" (Expand Search), "fop petruiiv OR petruiov OR petruuiiov OR petero OR peterov OR petruuiiuo 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 ((petriiv OR (petriov OR petruiiov)) OR (((petero OR peterov) OR petruiiuo) OR petr)) o.s.*.
