Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor", "dosde factor", "dose factorr", "dosex factor"
"de faito" » "de facto", "de fait", "de faits"
"de fact" » "de facto", "de fait", "e fact"
"e facto" » "de facto", "e factor", "ex facto"

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