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