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