Perhaps you should try some spelling variations:
"literaturas sin debate." » "literatura sin debate.", "literaturas en debate.", "literatura en debate.", "literaturas un debate."
"literaturas su debate." » "literaturas de debate.", "literaturas y debate.", "literaturas en debate.", "literaturas un debate.", "literaturas a debate."
"literaturas el debate." » "literaturas del debate.", "literatura el debate.", "literaturas en debate."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("literaturas sin debate.") OR ("literaturas su debate."))) or ("literaturas el debate."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("literaturas sin debate.") OR ("literaturas su debate."))) OR ("literaturas el debate.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"literaturas sin debate.\") OR (\"literaturas su debate.\"))) or (\"literaturas el debate.\"))".
• Removing quotes may allow a broader search: (((( literaturas sin debate. ) OR ( literaturas su debate. ))) or ( literaturas el debate. )).
• Adding a wildcard symbol may retrieve word variants: (((("literaturas sin debate.") OR ("literaturas su debate."))) or ("literaturas el debate."))*.
