• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"production management / https://id.loc.gov/authorities/subjects/sh85107216\") OR (\"introduction management / https://id.loc.gov/authorities/subjects/sh85107216\"))".
• Removing quotes may allow a broader search: (( production management / https://id.loc.gov/authorities/subjects/sh85107216 ) OR ( introduction management / https://id.loc.gov/authorities/subjects/sh85107216 )).
• Adding a wildcard symbol may retrieve word variants: (("production management / https://id.loc.gov/authorities/subjects/sh85107216") OR ("introduction management / https://id.loc.gov/authorities/subjects/sh85107216"))*.
