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