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