Perhaps you should try some spelling variations:
"fop petruv OR peteriuv OR petroov OR petru OR petrouo OR petr OR per o.s.*" » "fop petrov OR peteriuv OR petroov OR petru OR petrouo OR petr OR per o.s.*" (Expand Search), "fop petruv OR peteriuv OR petrov OR petru OR petrouo OR petr OR per o.s.*" (Expand Search), "fop pentruv OR peteriuv OR petroov OR pentru OR petrouo OR petr OR per o.s.*" (Expand Search), "fop petriv OR peteriuv OR petroov OR petri OR petrouo OR petr OR per o.s.*" (Expand Search), "fop peteruv OR peteriuv OR peteroov OR peteru OR peterouo OR peter OR per o.s.*" (Expand Search), "fop petriuv OR peteriuv OR petrioov OR petriu OR petriouo OR petri OR per o.s.*" (Expand Search), "fop petrouv OR peteriuv OR petrooov OR petrou OR petroouo OR petro OR per o.s.*" (Expand Search)

• Removing quotes may allow a broader search: fop ((petruv OR peteriuv) OR (((petroov OR petru) OR petrouo) OR (petr OR per))) o.s.*.
