Perhaps you should try some spelling variations:
"de factor" » "de facto", "e factor", "dose factor", "de factoor", "one factor"
"de falco" » "de facto"
"de faconor" » "de factoor", "la faconor", "en faconor"
"de facon" » "de facto", "la facon", "en facon"
"de fazer" » "de fer"
"de fact" » "de facto", "e fact", "one fact"
"de fait" » "de faits", "le fait", "se fait"

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 fact") OR ("de falco"))) OR ("de fait"))) OR ((((("de factor") OR ("de faconor"))) OR ((((("de facon") OR ("de fazer"))) OR ((("de factor") OR ("de faconor")))))))).
• Removing quotes may allow a broader search: (((((( de fact ) or ( de falco ))) or ( de fait ))) or ((((( de factor ) or ( de faconor ))) or ((((( de facon ) or ( de fazer ))) or ((( de factor ) or ( de faconor )))))))).
• Adding a wildcard symbol may retrieve word variants: (((((("de fact") or ("de falco"))) or ("de fait"))) or ((((("de factor") or ("de faconor"))) or ((((("de facon") or ("de fazer"))) or ((("de factor") or ("de faconor"))))))))*.
