Perhaps you should try some spelling variations:
"fop petriu OR peteru OR petruv OR petriv OR periv OR petriv OR petr o.s.*" » "fop peteriu OR peteru OR peteruv OR peteriv OR periv OR peteriv OR peter o.s.*" (Expand Search), "fop petriiu OR peteru OR petriuv OR petriiv OR periv OR petriiv OR petri o.s.*" (Expand Search), "fop petruiu OR peteru OR petruuv OR petruiv OR periv OR petruiv OR petru 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 ((petriu OR peteru) OR ((petruv OR (petriv OR periv)) OR (petriv OR petr))) o.s.*.
