Perhaps you should try some spelling variations:
"fop peteriv OR petriiiv OR petriiiv OR peteruuo OR peteri OR petriio OR petr o.s.*" » "fop peteriv OR peteriiiv OR peteriiiv OR peteruuo OR peteri OR peteriio OR peter o.s.*" (Expand Search), "fop peteriv OR petriiiiv OR petriiiiv OR peteruuo OR peteri OR petriiio OR petri o.s.*" (Expand Search), "fop peteriv OR petruiiiv OR petruiiiv OR peteruuo OR peteri OR petruiio 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 ((peteriv OR (petriiiv OR petriiiv)) OR (((peteruuo OR peteri) OR petriio) OR petr)) o.s.*.
