Perhaps you should try some spelling variations:
"literatura arabe _ ilam." » "literatura breve _ ilam.", "literatura de _ ilam."
"literatura al _ ilam." » "literatura el _ ilam.", "literatura del _ ilam.", "literatura de _ ilam."
"literatura e de isaac." » "literatura de de isaac.", "literatura en de isaac.", "literatura del de isaac.", "literatura y de isaac.", "literatura _ de isaac."

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 arabe _ ilam.") OR ("literatura al _ ilam."))) OR ("literatura e de isaac."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"literatura arabe _ ilam.\") OR (\"literatura al _ ilam.\"))) or (\"literatura e de isaac.\"))~".
• Removing quotes may allow a broader search: (((( literatura arabe _ ilam. ) OR ( literatura al _ ilam. ))) or ( literatura e de isaac. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("literatura arabe _ ilam.") OR ("literatura al _ ilam."))) or ("literatura e de isaac."))*.
