Perhaps you should try some spelling variations:
"fop petriov OR petruv OR peteruv OR petriiuv OR petruov OR petru OR petr o.s.*" » "fop peteriov OR peteruv OR peteruv OR peteriiuv OR peteruov OR peteru OR peter o.s.*" (Expand Search), "fop petriiov OR petriuv OR peteruv OR petriiiuv OR petriuov OR petriu OR petri o.s.*" (Expand Search), "fop petroiov OR petrouv OR peteruv OR petroiiuv OR petrouov OR petrou OR petro 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 ((((petriov OR (petruv OR peteruv)) OR petriiuv) OR petruov) OR (petru OR petr)) o.s.*.
