Perhaps you should try some spelling variations:
"literatura memoria _ isaac." » "literatura historia _ isaac.", "literatura moderna _ isaac.", "literatura america _ isaac."
"literatura del de isla." » "literatura en de isla.", "literatura del de isaac.", "literatura del dean isla."
"literatura de de isla." » "literatura de de isaac.", "literatura de fe isla.", "literatura de di isla."

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