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