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