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