Perhaps you should try some spelling variations:
"de fait" » "de fast", "de fact", "de fair"
"les faits" » "les fasts", "les facts", "les fairs", "les faith", "les fails"
"de facto" » "de factor", "de fact", "de facts"
"e facto" » "e factor", "e fact", "e facts"

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 ("les faits"))) OR ((("de facto") OR ("e facto")))).
• Removing quotes may allow a broader search: (((( de fait ) or ( les faits ))) or ((( de facto ) or ( e facto )))).
• Adding a wildcard symbol may retrieve word variants: (((("de fait") or ("les faits"))) or ((("de facto") or ("e facto"))))*.
