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", "sx factorr", "s5 factor", "sex falsor"
"ix factor" » "x factor", "six factors", "tax factor"
"dex facto" » "dux factor", "index factor", "dx factor", "d5 facto", "dex falso"
"ex facto" » "x factor", "5 facto", "ex falso"
"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 ((("e facto") OR ((("ex facto") OR ((((("ix factor") OR ("sex 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 (((\"e facto\") or (((\"ex facto\") or (((((\"ix factor\") OR (\"sex factor\"))) or (\"six factor\"))))))))) or (\"de fact\"))".
• Removing quotes may allow a broader search: (((((( de facto ) or ( dex facto ))) or ((( e facto ) or ((( ex facto ) or ((((( ix factor ) OR ( sex factor ))) or ( six factor ))))))))) or ( de fact )).
• Adding a wildcard symbol may retrieve word variants: (((((("de facto") or ("dex facto"))) or ((("e facto") or ((("ex facto") or ((((("ix factor") OR ("sex factor"))) or ("six factor"))))))))) or ("de fact"))*.
