• Performing a fuzzy search may retrieve terms with similar spellings: (((("50 ms decrease") OR ("50 ng decrease"))) OR ((("2 wt decrease") OR ("_ we decrease"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"50 ms decrease\") OR (\"50 ng decrease\"))) OR (((\"2 wt decrease\") OR (\"_ we decrease\"))))".
• Removing quotes may allow a broader search: (((( 50 ms decrease ) OR ( 50 ng decrease ))) OR ((( 2 wt decrease ) OR ( _ we decrease )))).
• Adding a wildcard symbol may retrieve word variants: (((("50 ms decrease") OR ("50 ng decrease"))) OR ((("2 wt decrease") OR ("_ we decrease"))))*.
