• If you are trying to use Boolean operators, they must be ALL CAPS: %((22business ethics) OR (business ethics)) %((20 poetry) OR (((2 poetry) OR (12 poetry)))) %((((2f early) OR (21 early))) OR (22 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22business ethics) or (business ethics)) %((20 poetry) or (((2 poetry) or (12 poetry)))) %((((2f early) OR (21 early))) or (22 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %((22business ethics) or (business ethics)) %((20 poetry) or (((2 poetry) or (12 poetry)))) %((((2f early) OR (21 early))) or (22 early)) works to 1800%22*.
