• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((mail's depressive) or (mild depressive)) disorder ) or ( being ((aggressive disorders) OR (depressive disorder)) ))".
• Adding a wildcard symbol may retrieve word variants: (( ((mail's depressive) or (mild depressive)) disorder ) or ( being ((aggressive disorders) OR (depressive disorder)) ))*.
