Perhaps you should try some spelling variations:
"literatura breve de isla." » "literatura en de isla.", "literatura del de isla.", "literatura breve de isaac."
"literatura e e islam." » "literatura en e islam.", "literatura del e islam.", "literatura e el islam.", "literatura e e islas.", "literatura e del islam.", "literatura de e islam.", "literatura e de islam.", "literatura el e islam."
"literatura de una idea." » "literatura de la idea."

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 e e islam.") OR ("literatura breve de isla."))) OR ("literatura de una idea."))~.
• Removing quotes may allow a broader search: (((( literatura e e islam. ) or ( literatura breve de isla. ))) or ( literatura de una idea. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("literatura e e islam.") or ("literatura breve de isla."))) or ("literatura de una idea."))*.
