Perhaps you should try some spelling variations:
"fop petriv OR petruiv OR petruuiv OR peteruiv OR petruio OR petr o.s.*" » "fop petriv OR petruiv OR petruuiv OR peterdi OR petruio OR petr o.s.*" (Expand Search), "fop peteriv OR peteruiv OR peteruuiv OR peteruiv OR peteruio OR peter o.s.*" (Expand Search), "fop petriiv OR petriuiv OR petriuuiv OR peteruiv OR petriuio OR petri o.s.*" (Expand Search), "fop petruiv OR petruuiv OR petruuuiv OR peteruiv OR petruuio 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 ((petruiv OR petruuiv) OR peteruiv)) OR (petruio OR petr)) o.s.*.
