• Performing a fuzzy search may retrieve terms with similar spellings: (("5 nn decrease") OR ((("5 nm decrease") OR ((("5 non decrease") OR ("a point decrease"))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"5 nn decrease\") OR (((\"5 nm decrease\") OR (((\"5 non decrease\") OR (\"a point decrease\"))))))*".
• Removing quotes may allow a broader search: (( 5 nn decrease ) OR ((( 5 nm decrease ) OR ((( 5 non decrease ) OR ( a point decrease ))))))*.
