Perhaps you should try some spelling variations:
alte » alter, alten
alternnr » alterrnnr, altenrnnr, alternans, alternant, alternano
alterrnahr » alterrrnahr, altenrrnahr, altenahr, altersjahr
alternr » alterrnr, altenrnr, altern, alterna, alternare
alle » all

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (alok OR ((alte OR alle) OR ((alternnr OR alterrnahr) OR alternr)))*.
