• Performing a fuzzy search may retrieve terms with similar spellings: (((("50 n decrease") OR ((("5 ng decrease") OR ("5 nm decrease"))))) OR ("50 we decrease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"50 n decrease\") OR (((\"5 ng decrease\") OR (\"5 nm decrease\"))))) OR (\"50 we decrease\"))".
• Removing quotes may allow a broader search: (((( 50 n decrease ) OR ((( 5 ng decrease ) OR ( 5 nm decrease ))))) OR ( 50 we decrease )).
• Adding a wildcard symbol may retrieve word variants: (((("50 n decrease") OR ((("5 ng decrease") OR ("5 nm decrease"))))) OR ("50 we decrease"))*.
