Perhaps you should try some spelling variations:
"de facteur" » "de facteurs", "le facteur", "du facteur", "de factoeur", "e facteur", "de falcoeur"
"de factr" » "de facto", "de fazer", "de facon", "de factor", "e factr", "de falcor"
"de fact" » "de facto", "e fact", "de falco"
"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 fait"))) OR ((("de factr") OR ("de facteur")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"de fact\") OR (\"de fait\"))) or (((\"de factr\") or (\"de facteur\"))))".
• Removing quotes may allow a broader search: (((( de fact ) OR ( de fait ))) or ((( de factr ) or ( de facteur )))).
• Adding a wildcard symbol may retrieve word variants: (((("de fact") OR ("de fait"))) or ((("de factr") or ("de facteur"))))*.
