Perhaps you should try some spelling variations:
"fop petru OR petru OR petr OR peteruo OR petruuo OR petruuuo OR petri o.s.*" » "fop pentru OR pentru OR petr OR peteruo OR pentruuo OR pentruuuo OR petri o.s.*" (Expand Search), "fop peteru OR peteru OR peter OR peteruo OR peteruuo OR peteruuuo OR peteri o.s.*" (Expand Search), "fop petrou OR petrou OR petro OR peteruo OR petrouuo OR petrouuuo OR petroi o.s.*" (Expand Search), "fop peru OR peru OR per OR peteruo OR peruuo OR peruuuo OR peri 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 ((petru OR petru) OR ((petr OR (peteruo OR (petruuo OR petruuuo))) OR petri)) o.s.*.
