Perhaps you should try some spelling variations:
"six factors" » "sex factors", "x factors", "sex factorss", "tax factors", "sx factors", "stax factors", "sx factorss"
"sex factor" » "sex factors", "x factor", "tax factor"
"six factor" » "sex factors", "x factor", "tax factor", "sx factor", "stax factor", "sx factors"
"dex facto" » "ex facto", "dux factor", "index factor"
"ix factor" » "x factor", "tax factor", "x factors"
"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 ((("e facto") OR ((((("ix factor") OR ("six factors"))) 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 (((((\"ix factor\") OR (\"six factors\"))) 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 ((((( ix factor ) OR ( six factors ))) 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 ((((("ix factor") OR ("six factors"))) or ((("sex factor") or ("six factor"))))))))) or ("de fact"))*.
