• If you are trying to use Boolean operators, they must be ALL CAPS: %22bible %2f n.t %2f ((matthew xxviii) OR (((((((matthew xiii) OR (matthew xvi))) OR (matthew xxiv))) OR (matthew xxii))))%2c 51 %((24 sermons) OR (2 sermons)) %2f early works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %2f ((matthew xxviii) or (((((((matthew xiii) OR (matthew xvi))) or (matthew xxiv))) or (matthew xxii))))%2c 51 %((24 sermons) or (2 sermons)) %2f early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %2f ((matthew xxviii) or (((((((matthew xiii) OR (matthew xvi))) or (matthew xxiv))) or (matthew xxii))))%2c 51 %((24 sermons) or (2 sermons)) %2f early works to 1800%22*.
