Perhaps you should try some spelling variations:
"literatura del _ islam." » "literatura de _ islam.", "literatura en _ islam."
"literatura el _ islam." » "literatura en _ islam.", "literatura e _ islam.", "literatura de _ islam."
"literatura el el islam." » "literatura en el islam.", "literatura e el islam.", "literatura de el islam.", "literatura es 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 el _ islam.") OR ("literatura del _ islam."))) or ("literatura el el islam."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("literatura el _ islam.") OR ("literatura del _ islam."))) OR ("literatura el el islam."))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"literatura el _ islam.\") OR (\"literatura del _ islam.\"))) or (\"literatura el el islam.\"))*".
• Removing quotes may allow a broader search: (((( literatura el _ islam. ) OR ( literatura del _ islam. ))) or ( literatura el el islam. ))*.
