Perhaps you should try some spelling variations:
"dex facto" » "sex factor", "dux factor", "index factor", "dsex factor", "dx factor", "d5 facto"
"ix factor" » "six factor", "x factor", "six factors"
"ex facto" » "sex factor", "x factor", "5 facto"
"de facto" » "de factor", "d5 facto", "de factors", "de faito", "de facono", "one facto", "d_ facto", "da facto", "d3 facto"
"e facto" » "e factor", "5 facto", "e factors", "_ facto", "a facto", "3 facto"
"de fact" » "de fait", "de facon", "one fact", "d_ fact", "da fact", "d3 fact"
"da fact" » "a fact", "data fact", "can fact"
"e fact" » "_ fact", "a fact", "3 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 facto") OR ("dex facto"))) OR ((((("e facto") OR ("e fact"))) OR ((("ex facto") OR ("ix factor"))))))) OR ((((("de fact") OR ("da fact"))) OR ("de falco")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"de facto\") or (\"dex facto\"))) or (((((\"e facto\") or (\"e fact\"))) or (((\"ex facto\") or (\"ix factor\"))))))) or (((((\"de fact\") OR (\"da fact\"))) or (\"de falco\"))))".
• Removing quotes may allow a broader search: (((((( de facto ) or ( dex facto ))) or ((((( e facto ) or ( e fact ))) or ((( ex facto ) or ( ix factor ))))))) or ((((( de fact ) OR ( da fact ))) or ( de falco )))).
• Adding a wildcard symbol may retrieve word variants: (((((("de facto") or ("dex facto"))) or ((((("e facto") or ("e fact"))) or ((("ex facto") or ("ix factor"))))))) or ((((("de fact") OR ("da fact"))) or ("de falco"))))*.
