• Performing a fuzzy search may retrieve terms with similar spellings: (("ct values decrease") OR ((("c marked decrease") OR ("c age increased"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ct values decrease\") OR (((\"c marked decrease\") OR (\"c age increased\"))))".
• Removing quotes may allow a broader search: (( ct values decrease ) OR ((( c marked decrease ) OR ( c age increased )))).
• Adding a wildcard symbol may retrieve word variants: (("ct values decrease") OR ((("c marked decrease") OR ("c age increased"))))*.
