Perhaps you should try some spelling variations:
"studie de sang" » "studie der sang", "studie die sang", "studie des sang", "studie de san", "studie de sans", "studie de sangre"
"studi de saggi" » "estudi de saggi", "studi del saggi", "studio de saggi", "studi di saggi", "studi e saggi", "studi de santi"
"studi de sang" » "estudi de sang", "studi del sang", "studio de sang", "studi de san", "studi de sans", "studi de sangre"

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: (("studi _ saggi") OR ((("studi de saggi") OR ((("studi de sang") OR ("studie de sang"))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"studi _ saggi\") or (((\"studi de saggi\") or (((\"studi de sang\") OR (\"studie de sang\"))))))*".
• Removing quotes may allow a broader search: (( studi _ saggi ) or ((( studi de saggi ) or ((( studi de sang ) OR ( studie de sang ))))))*.
