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