• If you are trying to use Boolean operators, they must be ALL CAPS: %22bible %2f n.t %2f ((matthew xiii) OR (matthew xxiv))%2c 51 %((6 sermons) OR (1 sermons)) %((12 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 xiii) OR (matthew xxiv))%2c 51 %((6 sermons) or (1 sermons)) %((12 early) or (11 early)) works to 1800%22*".
