Perhaps you should try some spelling variations:
2f public » 21 public, 20 public, 25 public
22 public » 3 public, 7 public, 8 public
12 public » 3 public, 7 public, 8 public
11 public » 1 public, 3 public, 7 public
5 public » 3 public, 4 public

Try widening your search to All Fields.

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: %22austria %((((2f public) OR (((((((22 public) OR (5 public))) OR (12 public))) OR (2 public))))) OR (11 public)) relations%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22austria %((((2f public) or (((((((22 public) OR (5 public))) or (12 public))) or (2 public))))) or (11 public)) relations%22".
• Adding a wildcard symbol may retrieve word variants: %22austria %((((2f public) or (((((((22 public) OR (5 public))) or (12 public))) or (2 public))))) or (11 public)) relations%22*.
