• If you are trying to use Boolean operators, they must be ALL CAPS: (("developmental psychology") OR ((("development psychology") OR ("development physiology")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"developmental psychology\") or (((\"development psychology\") OR (\"development physiology\"))))".
• Removing quotes may allow a broader search: (( developmental psychology ) or ((( development psychology ) OR ( development physiology )))).
• Adding a wildcard symbol may retrieve word variants: (("developmental psychology") or ((("development psychology") OR ("development physiology"))))*.
