• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %22 ((((matthew xiii) OR (matthew xvi))) or (matthew xxii))%2c 51 %((2f sermons) or (21 sermons)) %((2.1 early) or (1.1 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %22 ((((matthew xiii) OR (matthew xvi))) or (matthew xxii))%2c 51 %((2f sermons) or (21 sermons)) %((2.1 early) or (1.1 early)) works to 1800%22*.
