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