• Performing a fuzzy search may retrieve terms with similar spellings: (((("i marked decrease") OR ("i large decrease"))) OR ("ct values decrease"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"i marked decrease\") OR (\"i large decrease\"))) OR (\"ct values decrease\"))".
• Removing quotes may allow a broader search: (((( i marked decrease ) OR ( i large decrease ))) OR ( ct values decrease )).
• Adding a wildcard symbol may retrieve word variants: (((("i marked decrease") OR ("i large decrease"))) OR ("ct values decrease"))*.
