Perhaps you should try some spelling variations:
"fop peterov OR petriuv OR petrouv OR petru OR petroioiuo OR peterioiuo OR petr o.s.*" » "fop peterov OR peteriuv OR peterouv OR peteru OR peteroioiuo OR peterioiuo OR peter o.s.*" (Expand Search), "fop peterov OR petriiuv OR petriouv OR petriu OR petrioioiuo OR peterioiuo OR petri o.s.*" (Expand Search), "fop peterov OR petroiuv OR petroouv OR petrou OR petrooioiuo OR peterioiuo 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 ((peterov OR (petriuv OR petrouv)) OR ((petru OR (petroioiuo OR peterioiuo)) OR petr)) o.s.*.
