Perhaps you should try some spelling variations:
literatura arabe » literatura de, literatura e, literatura al
literatura breve » literatura de, literatura en, literatura del
arabe y » caribe y, arabes e
y islam » e islam, _ islam, el islam
e islas » el islam
e isla » de isla, e islam, e isela

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

• If you are trying to use Boolean operators, they must be ALL CAPS: "((\"literatura arabe y islam.\") or (\"literatura breve ((e isla) OR (e islas)).\"))".
• Removing quotes may allow a broader search: (( literatura arabe y islam. ) or ( literatura breve ((e isla) or (e islas)). )).
