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