Perhaps you should try some spelling variations:
"fop peterov OR perov OR petruuv OR peterv OR petro OR petriui OR petr o.s.*" » "fop peterov OR petrov OR petruuv OR peterv OR petro OR petriui OR petr o.s.*" (Expand Search), "fop peterov OR perov OR petruuv OR peterv OR petrov OR petriui OR petr o.s.*" (Expand Search), "fop peterov OR perov OR petruuv OR peterv OR petri OR petriui OR petr o.s.*" (Expand Search), "fop peterov OR perov OR petruuv OR peterv OR petru OR petriui OR petr o.s.*" (Expand Search), "fop peterov OR perov OR peteruuv OR peterv OR petero OR peteriui OR peter o.s.*" (Expand Search), "fop peterov OR perov OR petriuuv OR peterv OR petrio OR petriiui OR petri o.s.*" (Expand Search), "fop peterov OR perov OR petruuuv OR peterv OR petruo OR petruiui 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 ((((peterov OR perov) OR petruuv) OR peterv) OR ((petro OR petriui) OR petr)) o.s.*.
