• If you are trying to use Boolean operators, they must be ALL CAPS: %22bible %2f n.t %((2f matthew) OR (((2 matthew) OR (25 matthew)))) xxviii%((((2((c 51) OR (c 5))) OR (20 51))) OR (((c 51) OR (c 5)))) %2f sermons %21 early works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %((2f matthew) or (((2 matthew) or (25 matthew)))) xxviii%((((2((c 51) OR (c 5))) or (20 51))) or (((c 51) OR (c 5)))) %2f sermons %21 early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %((2f matthew) or (((2 matthew) or (25 matthew)))) xxviii%((((2((c 51) OR (c 5))) or (20 51))) or (((c 51) OR (c 5)))) %2f sermons %21 early works to 1800%22*.
