Perhaps you should try some spelling variations:
alte » alter, alten, alle
altennr » alternnr, altennnr, allennr, altenahr
alternnr » alterrnnr, altenrnnr, allernnr, alternans, alternant, alternano
altenund » alternund, altennund, allenund
altenrn » alternrn, altennrn, allenrn
altennrn » alternnrn, altennnrn, allennrn, altenahrn

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 (((altennr OR alternnr) OR altenund) OR (altenrn OR altennrn))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(alok or (alte or (((altennr or alternnr) or altenund) or (altenrn OR altennrn))))*".
