2c public » 22 public, c public, 20 public
21 public » 1 public, 11 public, 22 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: %22finance%((((2c public) OR (2 public))) OR (21 public)) %((23 green) OR (3 great)) britain %((ref history) OR (reef history)) %24 1688-1815%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22finance%((((2c public) OR (2 public))) or (21 public)) %((23 green) or (3 great)) britain %((ref history) or (reef history)) %24 1688-1815%22".
• Adding a wildcard symbol may retrieve word variants: %22finance%((((2c public) OR (2 public))) or (21 public)) %((23 green) or (3 great)) britain %((ref history) or (reef history)) %24 1688-1815%22*.
