Perhaps you should try some spelling variations:
"literatura breve de isaac." » "literatura en de isaac.", "literatura del de isaac.", "literatura e de isaac."
"literatura des x islam." » "literatura del x islam.", "literatura es x islam.", "literatura desde x islam.", "literatura des e islam.", "literatura des _ islam.", "literatura des el islam."
"literatura de x islam." » "literatura de e islam.", "literatura de _ islam.", "literatura de el islam.", "literatura del x islam.", "literatura de ex islam.", "literatura de ix islam."

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("literatura breve de isaac.") or ((("literatura des x islam.") OR ("literatura de x islam."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("literatura breve de isaac.") OR ((("literatura des x islam.") OR ("literatura de x islam."))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"literatura breve de isaac.\") or (((\"literatura des x islam.\") OR (\"literatura de x islam.\"))))*".
• Removing quotes may allow a broader search: (( literatura breve de isaac. ) or ((( literatura des x islam. ) OR ( literatura de x islam. ))))*.
