Perhaps you should try some spelling variations:
"alte" » "alten", "alle"
"altex" » "altenx", "allex", "baltex", "caltex", "alex"
"alter" » "altenr", "aller"
"allex" » "gallex", "vallex", "alle"
"ballen" » "ballet", "ballew", "balladen"

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 ((("altex" OR "allex") OR "alter") OR "ballen")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"alte\" or (((\"altex\" OR \"allex\") or \"alter\") or \"ballen\"))".
• Removing quotes may allow a broader search: ( alte or ((( altex OR allex ) or alter ) or ballen )).
• Adding a wildcard symbol may retrieve word variants: ("alte" or ((("altex" OR "allex") or "alter") or "ballen"))*.
