Perhaps you should try some spelling variations:
"ex facto" » "sex factor", "ix factor", "x factor"
"de faits" » "des faits", "de fait", "les faits"
"a fact" » "a face", "a factor"
"3 fact" » "3 facts", "3 fast", "3 face"

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 faits"))) OR ((("a fact") OR ("3 fact")))).
• Removing quotes may allow a broader search: (((((( de facto ) or ( ex facto ))) or ( de faits ))) or ((( a fact ) or ( 3 fact )))).
• Adding a wildcard symbol may retrieve word variants: (((((("de facto") or ("ex facto"))) or ("de faits"))) or ((("a fact") or ("3 fact"))))*.
