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