Perhaps you should try some spelling variations:
reef history » brief history, reeves history, imf history
reef fishery » reef fishes, reef fish
2c public » 21 public, c public, 20 public
23 green » 3 green, 13 green
2f 1688 » 2 1688, 22 1688, 24 1688

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