Perhaps you should try some spelling variations:
"literatura art_ del islam." » "literatura arte del islam.", "literatura parte del islam.", "literatura area del islam.", "literatura art_ el islam.", "literatura carta del islam."
"literatura de fe isaac." » "literatura de de isaac.", "literatura de e isaac.", "literatura de _ isaac."
"literatura y de islas." » "literatura y e islas.", "literatura y de isla.", "literatura y de islam."

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 fe isaac.") OR ("literatura y de islas."))) OR ("literatura art_ del islam."))~.
• Removing quotes may allow a broader search: (((( literatura de fe isaac. ) or ( literatura y de islas. ))) or ( literatura art_ del islam. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("literatura de fe isaac.") or ("literatura y de islas."))) or ("literatura art_ del islam."))*.
