Perhaps you should try some spelling variations:
"mode factor" » "model factor", "models factor", "model factory", "moe factor", "modose factor", "mode factores", "mode factr", "mode factsr"
"de factor" » "e factor", "dose factor", "de factores", "de factr", "de factsr"
"de faitor" » "de fair", "de fait", "de faits"
"les faits" » "des faits"
"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 faitor"))) OR ("mode factor"))) OR ("de facto"))) OR ("les faits")).
• Removing quotes may allow a broader search: (((((((( de factor ) or ( de faitor ))) or ( mode factor ))) or ( de facto ))) or ( les faits )).
• Adding a wildcard symbol may retrieve word variants: (((((((("de factor") or ("de faitor"))) or ("mode factor"))) or ("de facto"))) or ("les faits"))*.
