Perhaps you should try some spelling variations:
"mode factor" » "model factor", "models factor", "model factory", "mode factoor", "mode faitor", "moe factor"
"dose factor" » "noise factor", "one factor", "moore factor"
"les faits" » "des 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: (((((("mode factor") OR ("dose factor"))) OR ("les faits"))) OR ("de fact")).
• Removing quotes may allow a broader search: (((((( mode factor ) or ( dose factor ))) or ( les faits ))) or ( de fact )).
• Adding a wildcard symbol may retrieve word variants: (((((("mode factor") or ("dose factor"))) or ("les faits"))) or ("de fact"))*.
