Perhaps you should try some spelling variations:
"fop petriov OR petrv OR peterv OR petrov OR petero OR petru OR petr o.s.*" » "fop peteriov OR peterv OR peterv OR peterov OR petero OR peteru OR peter o.s.*" (Expand Search), "fop petriiov OR petriv OR peterv OR petriov OR petero OR petriu OR petri o.s.*" (Expand Search), "fop petroiov OR petrov OR peterv OR petroov OR petero OR petrou 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 (petrv OR peterv)) OR (((petrov OR petero) OR petru) OR petr)) o.s.*.
