• If you are trying to use Boolean operators, they must be ALL CAPS: %22natural theology %((((((2f early) OR (22 early))) OR (((((23 early) OR (13 early))) OR (3 early))))) OR (20 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22natural theology %((((((2f early) or (22 early))) or (((((23 early) OR (13 early))) or (3 early))))) or (20 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22natural theology %((((((2f early) or (22 early))) or (((((23 early) OR (13 early))) or (3 early))))) or (20 early)) works to 1800%22*.
