Perhaps you should try some spelling variations:
"ex facto" » "sex factor", "ix factor", "5 facto"
"de faits" » "des faits", "de fait", "les faits"
"de facto" » "da facto", "d5 facto", "d2 facto"
"e fact" » "a fact", "5 fact", "2 fact"
"_ fact" » "_ facts", "_ face"
"3 fact" » "3 facts", "3 fast", "3 face"
"x factor" » "x factors"
"a factor" » "a factors"

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 ((("ex facto") OR ((("x factor") OR ("a factor"))))))) OR ("de faits"))) OR ((((("e fact") OR ("_ fact"))) OR ("3 fact")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"de facto\") or (((\"ex facto\") or (((\"x factor\") OR (\"a factor\"))))))) or (\"de faits\"))) or (((((\"e fact\") or (\"_ fact\"))) or (\"3 fact\"))))".
• Removing quotes may allow a broader search: (((((( de facto ) or ((( ex facto ) or ((( x factor ) OR ( a factor ))))))) or ( de faits ))) or ((((( e fact ) or ( _ fact ))) or ( 3 fact )))).
• Adding a wildcard symbol may retrieve word variants: (((((("de facto") or ((("ex facto") or ((("x factor") OR ("a factor"))))))) or ("de faits"))) or ((((("e fact") or ("_ fact"))) or ("3 fact"))))*.
