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