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