• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"via large decrease\") OR (\"i larger decrease\"))) OR (\"ct values increased\"))".
• Removing quotes may allow a broader search: (((( via large decrease ) OR ( i larger decrease ))) OR ( ct values increased )).
• Adding a wildcard symbol may retrieve word variants: (((("via large decrease") OR ("i larger decrease"))) OR ("ct values increased"))*.
