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