Perhaps you should try some spelling variations:
governo universitario » jovenes universitarios, centro universitario, ensino universitario
modelo universitario » mundo universitario, profesor universitario, model university
biblioteca del » biblioteca della, biblioteca di
de prima » de primes, de prix, de prada

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "pluriversal – quaderni _ biblioteca del ((governo universitario) OR (modelo universitario)) de prima".
• Adding a wildcard symbol may retrieve word variants: pluriversal – quaderni _ biblioteca del ((governo universitario) OR (modelo universitario)) de prima*.
