Perhaps you should try some spelling variations:
"fop petru OR peterio OR peroio OR petrooio OR petruio OR petr OR petri o.s.*" » "fop pentru OR peterio OR peroio OR petrooio OR pentruio OR petr OR petri o.s.*" (Expand Search), "fop peteru OR peterio OR peroio OR peterooio OR peteruio OR peter OR peteri o.s.*" (Expand Search), "fop petrou OR peterio OR peroio OR petroooio OR petrouio OR petro OR petroi o.s.*" (Expand Search), "fop peru OR peterio OR peroio OR perooio OR peruio OR per 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 ((peterio OR ((peroio OR petrooio) OR petruio)) OR (petr OR petri))) o.s.*.
