Perhaps you should try some spelling variations:
atomization » atomizacion, atomisation, automatization
factorization » autorizacion, sectorizacion
optimisation » optimizacion, optimezation, utilisation
utilization » utilizacion, utilizaron, reutilizacion
optimization » optimizacion
same » some

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((atomization OR factorization) OR (optimisation OR utilization)) OR optimization) of same~.
• Adding a wildcard symbol may retrieve word variants: (((atomization or factorization) or (optimisation or utilization)) or optimization) of same*.
