Perhaps you should try some spelling variations:
confirmational » configurational
confirmatione » configuratione
confirmations » configurations
confirmation » configuration

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (conformational OR (((confirmational OR confirmatione) OR (confirmations OR confirmation)) OR vconformational)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(conformational or (((confirmational or confirmatione) or (confirmations OR confirmation)) or vconformational))".
• Adding a wildcard symbol may retrieve word variants: (conformational or (((confirmational or confirmatione) or (confirmations OR confirmation)) or vconformational))*.
