• If you are trying to use Boolean operators, they must be ALL CAPS: ("informationsmanager" OR ("innovationsmanagements" OR "informationsmanagement")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"informationsmanager\" or (\"innovationsmanagements\" OR \"informationsmanagement\"))".
• Removing quotes may allow a broader search: ( informationsmanager or ( innovationsmanagements OR informationsmanagement )).
• Adding a wildcard symbol may retrieve word variants: ("informationsmanager" or ("innovationsmanagements" OR "informationsmanagement"))*.
