Perhaps you should try some spelling variations:
"ex facto" » "sex factor", "ix factor", "x factor"
"de faits" » "des faits", "de fait", "les faits"
"3 facts" » "3 factors", "3 factor"
"de facto" » "d_ facto", "da facto", "d3 facto"
"e fact" » "_ fact", "a fact", "3 fact"

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