Perhaps you should try some spelling variations:
"model factor" » "models factor", "model fast"
"de faitor" » "de facto", "de fair", "de faits", "de faitsor", "le faitor", "se faitor"
"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 faitor") OR ("model factor")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"de fact\") OR (\"de fait\"))) or (((\"de faitor\") or (\"model factor\"))))".
• Removing quotes may allow a broader search: (((( de fact ) OR ( de fait ))) or ((( de faitor ) or ( model factor )))).
• Adding a wildcard symbol may retrieve word variants: (((("de fact") OR ("de fait"))) or ((("de faitor") or ("model factor"))))*.
