Perhaps you should try some spelling variations:
alte » alter, alten, alle
balterx » balterrx, baltenrx, ballerx, balter, baltex, balters
balternr » balterrnr, baltenrnr, ballernr, balter, balten, balters
ballernr » ballern, ballerno, ballerina

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: ((alte OR (balterx OR (balternr OR ballernr))) OR all).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((alte or (balterx or (balternr OR ballernr))) or all)".
• Adding a wildcard symbol may retrieve word variants: ((alte or (balterx or (balternr OR ballernr))) or all)*.
