• If you are trying to use Boolean operators, they must be ALL CAPS: %22humanities %3 bibliography %((22 private) OR (2.2 private)) collections %21 germany %((2 berlin) OR (2010 berlin)) %icf catalogs%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22humanities %3 bibliography %((22 private) OR (2.2 private)) collections %21 germany %((2 berlin) or (2010 berlin)) %icf catalogs%22".
• Adding a wildcard symbol may retrieve word variants: %22humanities %3 bibliography %((22 private) OR (2.2 private)) collections %21 germany %((2 berlin) or (2010 berlin)) %icf catalogs%22*.
