• If you are trying to use Boolean operators, they must be ALL CAPS: %22science %((((2f philosophy) OR (14 philosophy))) OR (((((23 philosophy) OR (13 philosophy))) OR (((2 philosophy) OR (((1 philosophy) OR (a philosophy))))))))%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22science %((((2f philosophy) or (14 philosophy))) or (((((23 philosophy) OR (13 philosophy))) or (((2 philosophy) or (((1 philosophy) or (a philosophy))))))))%22*".
