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