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