Perhaps you should try some spelling variations:
"six factor" » "six factors", "ix factor", "sex factor"
"dux factor" » "x factor", "ix factor", "sex factor"
"dex facto" » "sex factor", "index factor", "dsex factor", "dix factor", "dx factor"
"s5 factor" » "5 factor", "15 factor", "55 factor"
"ex facto" » "sex factor", "ix factor", "x factor"
"de facto" » "de factor", "de fact", "d5 facto", "de faito", "e facto", "de falcoo"
"e facto" » "e factor", "e fact", "5 facto"
"de fact" » "de fait", "e fact", "de falco"

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 ("dux factor"))))) OR ((("e facto") OR ((("ex facto") OR ((("s5 factor") OR ("six factor"))))))))) OR ("de fact")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"de facto\") or (((\"dex facto\") OR (\"dux factor\"))))) or (((\"e facto\") or (((\"ex facto\") or (((\"s5 factor\") or (\"six factor\"))))))))) or (\"de fact\"))".
• Removing quotes may allow a broader search: (((((( de facto ) or ((( dex facto ) OR ( dux factor ))))) or ((( e facto ) or ((( ex facto ) or ((( s5 factor ) or ( six factor ))))))))) or ( de fact )).
• Adding a wildcard symbol may retrieve word variants: (((((("de facto") or ((("dex facto") OR ("dux factor"))))) or ((("e facto") or ((("ex facto") or ((("s5 factor") or ("six factor"))))))))) or ("de fact"))*.
