Perhaps you should try some spelling variations:
alte » alter, alle
alten » altern, allen, alter
alternnr » alterrnnr, allernnr, alternans, alternant, alternano
alternr » alterrnr, allernr, altern, alternare, alternas
alternan » alterrnan, allernan, alternans, alternant, alternano, alternaten, alternansn
alterna » alterrna, allerna, alternate, alternans

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 alten) OR all) OR (alternnr OR ((alternr OR alternan) OR alterna))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(alok or (((alte or alten) or all) or (alternnr or ((alternr OR alternan) or alterna))))*".
