Perhaps you should try some spelling variations:
literatura breve » literatura de, literatura en, literatura e
literatura del » literatura de, literatura en
de islas » e islas, de isla, de islam
breve et » breve en, breve el, breve del
et islam » el islam, e islam, del islam
c islas » e islas, a islas

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( literatura del ((c islas) OR (de islas)). ) or ( literatura breve et islam. ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( literatura del ((c islas) OR (de islas)). ) OR ( literatura breve et islam. )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( literatura del ((c islas) OR (de islas)). ) or ( literatura breve et islam. ))".
• Adding a wildcard symbol may retrieve word variants: (( literatura del ((c islas) OR (de islas)). ) or ( literatura breve et islam. ))*.
