Perhaps you should try some spelling variations:
22 john » 2 john, 23 john
12 john » 1 john, 2 john, 10 john
20 1724 » 20 1721, 20 1734, 20 1764
20 1714 » 20th 1714
20 1794 » 28 1794, 2 1794, 20 1798

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: %22brown%((22 john) OR (12 john)) %((((20 1724) OR (20 1714))) OR (20 1794))-1791%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22brown%((22 john) or (12 john)) %((((20 1724) OR (20 1714))) or (20 1794))-1791%22".
• Adding a wildcard symbol may retrieve word variants: %22brown%((22 john) or (12 john)) %((((20 1724) OR (20 1714))) or (20 1794))-1791%22*.
