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