Perhaps you should try some spelling variations:
"dex facto" » "de facto", "sex factor", "dux factor", "dsex factor", "dix factor", "dde facto"
"ex facto" » "sex factor", "ix factor", "de facto"
"e factor" » "e factors", "one factor", "age factor", "de factor", "e factr", "5 factor"
"de fact" » "de facto", "de fait", "e fact"
"e facto" » "de facto", "e fact", "5 facto"

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