Perhaps you should try some spelling variations:
"literatura a el islam." » "literatura al el islam.", "literatura e el islam.", "literatura en el islam.", "literatura y el islam.", "literatura o el islam.", "literatura 2 el islam."
"literatura de un islam." » "literatura de e islam.", "literatura de _ islam."
"literatura de al islam." » "literatura de del islam.", "literatura de e 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 de un islam.") OR ("literatura de al islam."))) or ("literatura a el islam."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("literatura de un islam.") OR ("literatura de al islam."))) OR ("literatura a el islam.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"literatura de un islam.\") OR (\"literatura de al islam.\"))) or (\"literatura a el islam.\"))".
• Removing quotes may allow a broader search: (((( literatura de un islam. ) OR ( literatura de al islam. ))) or ( literatura a el islam. )).
• Adding a wildcard symbol may retrieve word variants: (((("literatura de un islam.") OR ("literatura de al islam."))) or ("literatura a el islam."))*.
