• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ct values increased\") OR (((\"c largest decrease\") OR (\"n marked decrease\"))))".
• Removing quotes may allow a broader search: (( ct values increased ) OR ((( c largest decrease ) OR ( n marked decrease )))).
• Adding a wildcard symbol may retrieve word variants: (("ct values increased") OR ((("c largest decrease") OR ("n marked decrease"))))*.
