• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"50 ms decrease\") OR (\"5 ng decrease\"))) OR (\"5 we decrease\"))".
• Removing quotes may allow a broader search: (((( 50 ms decrease ) OR ( 5 ng decrease ))) OR ( 5 we decrease )).
• Adding a wildcard symbol may retrieve word variants: (((("50 ms decrease") OR ("5 ng decrease"))) OR ("5 we decrease"))*.
