• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %2f ((((matthew xxviii) or (matthew xxv))) or (((matthew xxii) or (matthew xvi))))%((24 51) or (((((c 51) OR (c 1))) or (_ 51)))) %2f sermons %2f early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %2f ((((matthew xxviii) or (matthew xxv))) or (((matthew xxii) or (matthew xvi))))%((24 51) or (((((c 51) OR (c 1))) or (_ 51)))) %2f sermons %2f early works to 1800%22*.
