Perhaps you should try some spelling variations:
alte » alter, alten
alternnr » alterrnnr, altenrnnr, alternans, alternant, alternano
alternahr » alterrnahr, altenrnahr, altenahr, alternate, alternans
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 alternahr) OR alternr)))*.
