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