Perhaps you should try some spelling variations:
"de facteur" » "de facteurs", "le facteur", "du facteur"
"de faits" » "des faits", "les faits", "de traits", "le faits", "du faits", "de fairs"
"de fait" » "le fait", "du fait", "de fair"
"se fait" » "le 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 fait") OR ("se fait"))) OR ("de faits"))) OR ("de facteur"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"de fait\") OR (\"se fait\"))) or (\"de faits\"))) or (\"de facteur\"))*".
• Removing quotes may allow a broader search: (((((( de fait ) OR ( se fait ))) or ( de faits ))) or ( de facteur ))*.
