Perhaps you should try some spelling variations:
"fop peteruv OR petriv OR petriiv OR periiv OR petro OR peteri OR petr o.s.*" » "fop peteruv OR petriv OR petriiv OR periiv OR petrov OR peteri OR petr o.s.*" (Expand Search), "fop peteruv OR petriv OR petriiv OR periiv OR petri OR peteri OR petr o.s.*" (Expand Search), "fop peteruv OR petriv OR petriiv OR periiv OR petru OR peteri OR petr o.s.*" (Expand Search), "fop peteruv OR peteriv OR peteriiv OR periiv OR petero OR peteri OR peter o.s.*" (Expand Search), "fop peteruv OR petriiv OR petriiiv OR periiv OR petrio OR peteri OR petri o.s.*" (Expand Search), "fop peteruv OR petruiv OR petruiiv OR periiv OR petruo OR peteri 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 ((peteruv OR (petriv OR (petriiv OR periiv))) OR ((petro OR peteri) OR petr)) o.s.*.
