• If you are trying to use Boolean operators, they must be ALL CAPS: %22humanities %23 bibliography %((((21 private) OR (2 private))) OR (22 private)) collections %11 germany %2f berlin %((icf catalogs) OR (co catalogs))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22humanities %23 bibliography %((((21 private) OR (2 private))) or (22 private)) collections %11 germany %2f berlin %((icf catalogs) or (co catalogs))%22".
• Adding a wildcard symbol may retrieve word variants: %22humanities %23 bibliography %((((21 private) OR (2 private))) or (22 private)) collections %11 germany %2f berlin %((icf catalogs) or (co catalogs))%22*.
