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

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 automatization) or factorization) or (optimisation or optimization)) of hace~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((atomization OR automatization) OR factorization) OR (optimisation OR optimization)) of hace*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((atomization OR automatization) or factorization) or (optimisation or optimization)) of hace*".
