Perhaps you should try some spelling variations:
optimisation » optimizacion, optimezation, utilisation
optimization » optimizacion
atomization » atomizacion, atomisation, customization
factorization » autorizacion, sectorizacion
automatization » automatizacion, laautomatizacion, automatizado
same » some

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((optimisation OR optimization) or (atomization or factorization)) or automatization) of same~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((optimisation OR optimization) OR (atomization OR factorization)) OR automatization) of same.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((optimisation OR optimization) or (atomization or factorization)) or automatization) of same".
• Adding a wildcard symbol may retrieve word variants: (((optimisation OR optimization) or (atomization or factorization)) or automatization) of same*.
