Perhaps you should try some spelling variations:
ref history » reef history, bief history, imf history
21 public » 1 public, 11 public, 22 public
23 green » 3 green
13 green » 3 green
24 1688 » 2 1688, 4 1688, 22 1688

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%((21 public) OR (2 public)) %((((23 green) OR (13 green))) OR (3 great)) britain %((ref history) OR (brief history)) %24 1688-1815%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22finance%((21 public) or (2 public)) %((((23 green) or (13 green))) or (3 great)) britain %((ref history) OR (brief history)) %24 1688-1815%22".
• Adding a wildcard symbol may retrieve word variants: %22finance%((21 public) or (2 public)) %((((23 green) or (13 green))) or (3 great)) britain %((ref history) OR (brief history)) %24 1688-1815%22*.
