Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor", "dose factr", "dose factsr"
"de faito" » "de faits", "de fato", "de faire", "de faitso", "le faito", "se faito"
"de fait" » "de faits", "le fait", "se fait"
"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: (("dose factor") OR ((("de fait") OR ((("de facto") OR ("de faito")))))).
• Removing quotes may allow a broader search: (( dose factor ) or ((( de fait ) or ((( de facto ) or ( de faito )))))).
• Adding a wildcard symbol may retrieve word variants: (("dose factor") or ((("de fait") or ((("de facto") or ("de faito"))))))*.
