• Performing a fuzzy search may retrieve terms with similar spellings: (((("c largest decrease") OR ("b large decrease"))) OR ("c cases increased"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"c largest decrease\") OR (\"b large decrease\"))) OR (\"c cases increased\"))*".
• Removing quotes may allow a broader search: (((( c largest decrease ) OR ( b large decrease ))) OR ( c cases increased ))*.
