• If you are trying to use Boolean operators, they must be ALL CAPS: %22science %((((20 philosophy) OR (24 philosophy))) OR (((((23 philosophy) OR (13 philosophy))) OR (((a philosophy) OR (((6 philosophy) OR (6 philosophie))))))))%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22science %((((20 philosophy) or (24 philosophy))) or (((((23 philosophy) or (13 philosophy))) or (((a philosophy) or (((6 philosophy) OR (6 philosophie))))))))%22*".
