• Performing a fuzzy search may retrieve terms with similar spellings: (((("100 ng decrease") OR ("100 mg decrease"))) OR ((("5 _ decrease") OR ("_ fc decrease"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"100 ng decrease\") OR (\"100 mg decrease\"))) OR (((\"5 _ decrease\") OR (\"_ fc decrease\"))))".
• Removing quotes may allow a broader search: (((( 100 ng decrease ) OR ( 100 mg decrease ))) OR ((( 5 _ decrease ) OR ( _ fc decrease )))).
• Adding a wildcard symbol may retrieve word variants: (((("100 ng decrease") OR ("100 mg decrease"))) OR ((("5 _ decrease") OR ("_ fc decrease"))))*.
