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