Perhaps you should try some spelling variations:
"fop petrov OR peteriuov OR petrou OR petruiov OR peteriiuo OR peteruuo OR petr o.s.*" » "fop peterov OR peteriuov OR peterou OR peteruiov OR peteriiuo OR peteruuo OR peter o.s.*" (Expand Search), "fop petriov OR peteriuov OR petriou OR petriuiov OR peteriiuo OR peteruuo OR petri o.s.*" (Expand Search), "fop petruov OR peteriuov OR petruou OR petruuiov OR peteriiuo OR peteruuo 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 ((petrov OR peteriuov) OR (((petrou OR petruiov) OR (peteriiuo OR peteruuo)) OR petr)) o.s.*.
