• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"a largest decrease\") OR (\"a latest decrease\"))) OR (\"c marked decrease\"))".
• Removing quotes may allow a broader search: (((( a largest decrease ) OR ( a latest decrease ))) OR ( c marked decrease )).
• Adding a wildcard symbol may retrieve word variants: (((("a largest decrease") OR ("a latest decrease"))) OR ("c marked decrease"))*.
