• Performing a fuzzy search may retrieve terms with similar spellings: (((("50 ms decrease") OR ("10 ng decrease"))) OR ((("_ we decrease") OR ("_ eb decrease"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"50 ms decrease\") OR (\"10 ng decrease\"))) OR (((\"_ we decrease\") OR (\"_ eb decrease\"))))".
• Removing quotes may allow a broader search: (((( 50 ms decrease ) OR ( 10 ng decrease ))) OR ((( _ we decrease ) OR ( _ eb decrease )))).
• Adding a wildcard symbol may retrieve word variants: (((("50 ms decrease") OR ("10 ng decrease"))) OR ((("_ we decrease") OR ("_ eb decrease"))))*.
