• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"advanced in chemistry spaces\") OR (\"advanced in chemistry snakes\"))) or (\"advanced in chemistry special\"))".
• Removing quotes may allow a broader search: (((( advanced in chemistry spaces ) OR ( advanced in chemistry snakes ))) or ( advanced in chemistry special )).
• Adding a wildcard symbol may retrieve word variants: (((("advanced in chemistry spaces") OR ("advanced in chemistry snakes"))) or ("advanced in chemistry special"))*.
