Perhaps you should try some spelling variations:
"ex facto" » "sex factor", "ix factor", "de facto"
"de facon" » "de facto", "de falco", "la facon"
"e facto" » "de facto", "e factor", "e fact"
"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: (((("e facto") OR ("ex facto"))) OR ((((("de fact") OR ("de facon"))) OR ("de fait")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"e facto\") OR (\"ex facto\"))) or (((((\"de fact\") or (\"de facon\"))) or (\"de fait\"))))".
• Removing quotes may allow a broader search: (((( e facto ) OR ( ex facto ))) or ((((( de fact ) or ( de facon ))) or ( de fait )))).
• Adding a wildcard symbol may retrieve word variants: (((("e facto") OR ("ex facto"))) or ((((("de fact") or ("de facon"))) or ("de fait"))))*.
