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