Perhaps you should try some spelling variations:
"ex facto" » "sex factor", "ix factor", "x factor"
"de facto" » "e facto", "de falcoo", "de facono"
"de fact" » "e fact", "de falco", "de facon"
"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 facto") OR ("ex facto"))) OR ((("de fact") OR ("de fait")))).
• Removing quotes may allow a broader search: (((( de facto ) or ( ex facto ))) or ((( de fact ) or ( de fait )))).
• Adding a wildcard symbol may retrieve word variants: (((("de facto") or ("ex facto"))) or ((("de fact") or ("de fait"))))*.
