Perhaps you should try some spelling variations:
"dex facto" » "sex factor", "dux factor", "index factor", "dsex factor", "dix factor", "dx factor"
"ex facto" » "sex factor", "ix factor", "x factor"
"de facto" » "de factor", "de fact", "d5 facto"
"e facto" » "e factor", "e fact", "5 facto"
"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 ("dex facto"))) OR ((("e facto") OR ("ex facto"))))) OR ("de fait")).
• Removing quotes may allow a broader search: (((((( de facto ) or ( dex facto ))) or ((( e facto ) or ( ex facto ))))) or ( de fait )).
• Adding a wildcard symbol may retrieve word variants: (((((("de facto") or ("dex facto"))) or ((("e facto") or ("ex facto"))))) or ("de fait"))*.
