Perhaps you should try some spelling variations:
ambulantenr » ambulanter, ambulanzen, ambulantem
ambulantes » ambulanter, ambulant
ambulance » ambulanter, imbalance
ambulantennr » ambulanter, ambulanzen, ambulantem
ambulantennnr » ambulanter

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: ( (ambulante OR ambulanten) OR ( (ambulantenr OR (ambulantes OR ambulance)) OR (ambulantennr OR ambulantennnr) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "( (ambulante or ambulanten) or ( (ambulantenr or (ambulantes OR ambulance)) or (ambulantennr or ambulantennnr) ))".
• Adding a wildcard symbol may retrieve word variants: ( (ambulante or ambulanten) or ( (ambulantenr or (ambulantes OR ambulance)) or (ambulantennr or ambulantennnr) ))*.
