• If you are trying to use Boolean operators, they must be ALL CAPS: %22humanities %2f bibliography %((2f private) OR (3 private)) collections %1918 germany %((29 berlin) OR (2 berlin)) %((icf catalogs) OR (((co catalogs) OR (_ catalogs))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22humanities %2f bibliography %((2f private) or (3 private)) collections %1918 germany %((29 berlin) OR (2 berlin)) %((icf catalogs) or (((co catalogs) or (_ catalogs))))%22".
• Adding a wildcard symbol may retrieve word variants: %22humanities %2f bibliography %((2f private) or (3 private)) collections %1918 germany %((29 berlin) OR (2 berlin)) %((icf catalogs) or (((co catalogs) or (_ catalogs))))%22*.
