• Performing a fuzzy search may retrieve terms with similar spellings: (("50 pp decrease") OR ((("k _ decrease") OR ((("a point decrease") OR ("_ point decrease"))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"50 pp decrease\") OR (((\"k _ decrease\") OR (((\"a point decrease\") OR (\"_ point decrease\"))))))*".
• Removing quotes may allow a broader search: (( 50 pp decrease ) OR ((( k _ decrease ) OR ((( a point decrease ) OR ( _ point decrease ))))))*.
