Perhaps you should try some spelling variations:
"ex facto" » "sex factor", "ix factor", "de facto"
"e facto" » "de facto", "e factor", "5 facto", "_ facto", "a facto", "3 facto"
"de fact" » "de facto", "de fait", "de falco", "d_ fact", "da fact", "d3 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: (((("e facto") OR ("ex facto"))) OR ((("de fact") OR ("e fact")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"e facto\") or (\"ex facto\"))) or (((\"de fact\") OR (\"e fact\"))))".
• Removing quotes may allow a broader search: (((( e facto ) or ( ex facto ))) or ((( de fact ) OR ( e fact )))).
• Adding a wildcard symbol may retrieve word variants: (((("e facto") or ("ex facto"))) or ((("de fact") OR ("e fact"))))*.
