Perhaps you should try some spelling variations:
"literatura arabe et islam." » "literatura breve et islam.", "literatura e et islam.", "literatura al et islam.", "literatura arabe en islam.", "literatura arabe e islam.", "literatura arabe el islam.", "literatura arabe del islam."
"literatura de de islam." » "literatura de del islam.", "literatura de de isla.", "literatura de e islam.", "literatura de di islam."
"literatura de fe islam." » "literatura de e islam.", "literatura de del islam.", "literatura de el islam."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("literatura arabe et islam.") or ((("literatura de de islam.") OR ("literatura de fe islam."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("literatura arabe et islam.") OR ((("literatura de de islam.") OR ("literatura de fe islam."))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"literatura arabe et islam.\") or (((\"literatura de de islam.\") OR (\"literatura de fe islam.\"))))*".
• Removing quotes may allow a broader search: (( literatura arabe et islam. ) or ((( literatura de de islam. ) OR ( literatura de fe islam. ))))*.
