Perhaps you should try some spelling variations:
"fop peterov OR petruv OR peterv OR petro OR petru OR peru OR petr o.s.*" » "fop peterov OR petruv OR peterv OR petrov OR petru OR peru OR petr o.s.*" (Expand Search), "fop peterov OR petruv OR peterv OR petri OR petru OR peru OR petr o.s.*" (Expand Search), "fop peterov OR petruv OR peterv OR petro OR petru OR per OR petr o.s.*" (Expand Search), "fop peterov OR peteruv OR peterv OR petero OR peteru OR peru OR peter o.s.*" (Expand Search), "fop peterov OR petriuv OR peterv OR petrio OR petriu OR peru OR petri o.s.*" (Expand Search), "fop peterov OR peruv OR peterv OR pero OR peru OR peru OR per o.s.*" (Expand Search)
