Perhaps you should try some spelling variations:
studie der » studium der
"studie de santi" » "studie die santi", "studie des santi", "studies de santi", "studie de santis", "studie de sante", "studie de santo"
"studie de santa" » "studie die santa", "studie des santa", "studies de santa", "studie de sante", "studie de sainte", "studie de saint"
studi de » estudi de, studi del, studio de

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: (((("studie de santi") OR ("studie de santa"))) OR ("((studi de) or (studie der)) saggi")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"studie de santi\") OR (\"studie de santa\"))) or (\"((studi de) or (studie der)) saggi\"))".
• Removing quotes may allow a broader search: (((( studie de santi ) OR ( studie de santa ))) or ( ((studi de) or (studie der)) saggi )).
• Adding a wildcard symbol may retrieve word variants: (((("studie de santi") OR ("studie de santa"))) or ("((studi de) or (studie der)) saggi"))*.
