Perhaps you should try some spelling variations:
2f public » 21 public, 25 public, 23 public
20 public » 10 public, 21 public, 25 public
22 public » 12 public, 3 public, 5 public
11 public » 1 public, 3 public, 7 public
8 public » 3 public, 4 public, 5 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 (20 public))) OR (((22 public) OR (2 public))))) OR (((11 public) OR (8 public)))) relations%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22austria %((((((2f public) or (20 public))) or (((22 public) or (2 public))))) or (((11 public) OR (8 public)))) relations%22".
• Adding a wildcard symbol may retrieve word variants: %22austria %((((((2f public) or (20 public))) or (((22 public) or (2 public))))) or (((11 public) OR (8 public)))) relations%22*.
