Perhaps you should try some spelling variations:
"fop peteriiiv OR petruv OR petro OR petriov OR petrui OR peteruo OR petr o.s.*" » "fop peteriiiv OR petruv OR petrov OR petriov OR petrui OR peteruo OR petr o.s.*" (Expand Search), "fop peteriiiv OR petruv OR petri OR petriov OR petrui OR peteruo OR petr o.s.*" (Expand Search), "fop peteriiiv OR petruv OR petru OR petriov OR petrui OR peteruo OR petr o.s.*" (Expand Search), "fop peteriiiv OR peteruv OR petero OR peteriov OR peterui OR peteruo OR peter o.s.*" (Expand Search), "fop peteriiiv OR petriuv OR petrio OR petriiov OR petriui OR peteruo OR petri o.s.*" (Expand Search), "fop peteriiiv OR petruuv OR petruo OR petruiov OR petruui OR peteruo OR petru o.s.*" (Expand Search)

• Removing quotes may allow a broader search: fop ((peteriiiv OR petruv) OR ((((petro OR petriov) OR petrui) OR peteruo) OR petr)) o.s.*.
