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