Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor"
"de faito" » "de facto", "de fait", "de fato"
"de faits" » "des faits", "de fait", "les faits"
"de fact" » "de facto", "de fait", "e fact"

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