Perhaps you should try some spelling variations:
"fop petriv OR peteruov OR petruv OR peteruv OR petruoi OR petrio OR petr o.s.*" » "fop petriv OR petrov OR petruv OR peteruv OR petruoi OR petrio OR petr o.s.*" (Expand Search), "fop peteriv OR peteruov OR peteruv OR peteruv OR peteruoi OR peterio OR peter o.s.*" (Expand Search), "fop petriiv OR peteruov OR petriuv OR peteruv OR petriuoi OR petriio OR petri o.s.*" (Expand Search), "fop petruiv OR peteruov OR petruuv OR peteruv OR petruuoi OR petruio 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 (((petriv OR peteruov) OR (petruv OR peteruv)) OR ((petruoi OR petrio) OR petr)) o.s.*.
