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