Perhaps you should try some spelling variations:
"fop petruov OR petriiov OR pero OR petru OR peteru OR peteriuv OR petr o.s.*" » "fop petruov OR petrov OR pero OR petru OR peteru OR peteriuv OR petr o.s.*" (Expand Search), "fop peteruov OR peteriiov OR pero OR peteru OR peteru OR peteriuv OR peter o.s.*" (Expand Search), "fop petriuov OR petriiiov OR pero OR petriu OR peteru OR peteriuv OR petri o.s.*" (Expand Search), "fop petrouov OR petroiiov OR pero OR petrou OR peteru OR peteriuv 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 ((petruov OR petriiov) OR (((pero OR (petru OR peteru)) OR peteriuv) OR petr)) o.s.*.
