Perhaps you should try some spelling variations:
"mode factor" » "model factor", "models factor", "model factory", "mode factr"
"de factoor" » "de facteur", "de factor"
"de faito" » "de fait", "de fato", "de faire"
"de faits" » "des faits", "de fait", "les faits"
"de facts" » "cbe facts", "de fautes", "tie facts"
"de facto" » "de 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 factoor") OR ("mode factor"))) OR ((("de faito") OR ("de faits"))))) OR ((("de facto") OR ("de facts")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"de factoor\") or (\"mode factor\"))) or (((\"de faito\") or (\"de faits\"))))) or (((\"de facto\") OR (\"de facts\"))))".
• Removing quotes may allow a broader search: (((((( de factoor ) or ( mode factor ))) or ((( de faito ) or ( de faits ))))) or ((( de facto ) OR ( de facts )))).
• Adding a wildcard symbol may retrieve word variants: (((((("de factoor") or ("mode factor"))) or ((("de faito") or ("de faits"))))) or ((("de facto") OR ("de facts"))))*.
