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