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