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