Perhaps you should try some spelling variations:
"literatura m_ del islam." » "literatura ma del islam.", "literatura mas del islam.", "literatura de del islam.", "literatura m_ el islam."
"literatura a de isla." » "literatura al de isla.", "literatura e de isla.", "literatura de de isla.", "literatura a de isaac.", "literatura y de isla.", "literatura o de isla."
"literatura _ de ilam." » "literatura _ de islam.", "literatura _ de chilam."

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 _ de ilam.") OR ((("literatura m_ del islam.") OR ("literatura a de isla."))))~.
• Removing quotes may allow a broader search: (( literatura _ de ilam. ) or ((( literatura m_ del islam. ) or ( literatura a de isla. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("literatura _ de ilam.") or ((("literatura m_ del islam.") or ("literatura a de isla."))))*.
