• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ends bibliographic series\") OR (\"hands bibliographic series\"))".
• Removing quotes may allow a broader search: (( ends bibliographic series ) OR ( hands bibliographic series )).
• Adding a wildcard symbol may retrieve word variants: (("ends bibliographic series") OR ("hands bibliographic series"))*.
