Perhaps you should try some spelling variations:
"dose factsr" » "dose factor"
"de factor" » "e factor", "dose factor", "mode factor", "de factr", "de factsr"
"de fait" » "de faits", "se fait", "du fait"
"le fait" » "le faict"
"de facto" » "de fact", "de facts"

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