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