Perhaps you should try some spelling variations:
"de factor" » "de facto", "e factor", "dose factor", "de factoor", "de falcoor"
"de faito" » "de facto", "de faits", "de fato", "de faitso", "le faito", "se faito"
"de fait" » "de faits", "le fait", "se fait"
"de fact" » "de facto", "e fact", "de falco"

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: (((("de factor") OR ((("de faito") OR ("de fait"))))) OR ("de fact")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"de factor\") or (((\"de faito\") OR (\"de fait\"))))) or (\"de fact\"))".
• Removing quotes may allow a broader search: (((( de factor ) or ((( de faito ) OR ( de fait ))))) or ( de fact )).
• Adding a wildcard symbol may retrieve word variants: (((("de factor") or ((("de faito") OR ("de fait"))))) or ("de fact"))*.
