Perhaps you should try some spelling variations:
optimisation » optimizacion, optimezation, utilisation
optimization » optimizacion
atomization » atomizacion, atomisation, customization
automatization » automatizacion, laautomatizacion, automatizado
factorization » autorizacion, sectorizacion
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 automatization) or factorization)) of same~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((optimisation OR optimization) OR ((atomization OR automatization) OR factorization)) of same.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((optimisation OR optimization) or ((atomization or automatization) or factorization)) of same".
• Adding a wildcard symbol may retrieve word variants: ((optimisation OR optimization) or ((atomization or automatization) or factorization)) of same*.
