Perhaps you should try some spelling variations:
"de factor" » "de facto", "e factor", "dose factor", "de factoor", "de falcoor"
"de falcor" » "de falco", "die falcon", "de facon"
"de fact" » "de facto", "e fact", "de falco"
"de fait" » "de faits", "le fait", "se fait"

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 fact") OR ("de fait"))) OR ((("de factor") OR ((("de falcor") OR ("de factor")))))).
• Removing quotes may allow a broader search: (((( de fact ) or ( de fait ))) or ((( de factor ) or ((( de falcor ) or ( de factor )))))).
• Adding a wildcard symbol may retrieve word variants: (((("de fact") or ("de fait"))) or ((("de factor") or ((("de falcor") or ("de factor"))))))*.
