• Performing a fuzzy search may retrieve terms with similar spellings: (("50 a decrease") OR ((("100 ng decrease") OR ("10 we decrease"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"50 a decrease\") OR (((\"100 ng decrease\") OR (\"10 we decrease\"))))".
• Removing quotes may allow a broader search: (( 50 a decrease ) OR ((( 100 ng decrease ) OR ( 10 we decrease )))).
• Adding a wildcard symbol may retrieve word variants: (("50 a decrease") OR ((("100 ng decrease") OR ("10 we decrease"))))*.
