Perhaps you should try some spelling variations:
"fop peterov OR petri OR petru OR petrio OR peru OR peteriiu OR peruo OR petr o.s.*" » "fop peterov OR petri OR petru OR petrio OR per OR peteriiu OR pero OR petr o.s.*" (Expand Search), "fop peterov OR petri OR petru OR petrio OR peru OR peterdi OR peruo OR petr o.s.*" (Expand Search), "fop peterov OR peteri OR peteru OR peterio OR peru OR peteriiu OR peruo OR peter o.s.*" (Expand Search), "fop peterov OR petroi OR petrou OR petroio OR peru OR peteriiu OR peruo OR petro o.s.*" (Expand Search), "fop peterov OR peri OR peru OR perio OR peru OR peteriiu OR peruo OR per o.s.*" (Expand Search)
