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

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: "\"((\\"literatura arabe ((y islam) OR (_ islam)).\\") or (\\"literatura breve e isla.\\"))\"".
• Removing quotes may allow a broader search: (( literatura arabe ((y islam) OR (_ islam)). ) or ( literatura breve e isla. )).
