Perhaps you should try some spelling variations:
"de fact" » "de facto", "de falco", "de facon", "d_ fact", "da fact", "d3 fact"
"de fait" » "de faits", "se fait", "du fait"
"le fait" » "le faict"
"one factor" » "on_ factor", "ona factor", "on3 factor", "one factors"
"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: (("one factor") OR ((((("de fact") OR ((("de fait") OR ("le fait"))))) OR ("e fact")))).
• Removing quotes may allow a broader search: (( one factor ) or ((((( de fact ) or ((( de fait ) or ( le fait ))))) or ( e fact )))).
• Adding a wildcard symbol may retrieve word variants: (("one factor") or ((((("de fact") or ((("de fait") or ("le fait"))))) or ("e fact"))))*.
