• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"nut shells / http://id.loc.gov/authorities/james/n93002992\") OR (\"fruit shells / http://id.loc.gov/authorities/james/n93002992\"))".
• Removing quotes may allow a broader search: (( nut shells / http://id.loc.gov/authorities/james/n93002992 ) OR ( fruit shells / http://id.loc.gov/authorities/james/n93002992 )).
• Adding a wildcard symbol may retrieve word variants: (("nut shells / http://id.loc.gov/authorities/james/n93002992") OR ("fruit shells / http://id.loc.gov/authorities/james/n93002992"))*.
