• If you are trying to use Boolean operators, they must be ALL CAPS: %22humanities %2f bibliography %((2f private) OR (3 private)) collections %11 germany %((((29 berlin) OR (39 berlin))) OR (99 berlin)) %((icf catalogs) OR (co catalogs))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22humanities %2f bibliography %((2f private) or (3 private)) collections %11 germany %((((29 berlin) OR (39 berlin))) or (99 berlin)) %((icf catalogs) or (co catalogs))%22".
• Adding a wildcard symbol may retrieve word variants: %22humanities %2f bibliography %((2f private) or (3 private)) collections %11 germany %((((29 berlin) OR (39 berlin))) or (99 berlin)) %((icf catalogs) or (co catalogs))%22*.
