• If you are trying to use Boolean operators, they must be ALL CAPS: %22bible %2f n.t %((2f matthew) OR (15 matthew)) xxviii%c 51 %2 sermons %((21 early) OR (11 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 (15 matthew)) xxviii%c 51 %2 sermons %((21 early) OR (11 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %((2f matthew) or (15 matthew)) xxviii%c 51 %2 sermons %((21 early) OR (11 early)) works to 1800%22*.
