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