Perhaps you should try some spelling variations:
"mode factor" » "model factor", "models factor", "model factory"
"de factsr" » "de facteur", "de facto", "de factor", "cbe factsr", "de fautesr"
"de facts" » "de facto", "cbe facts", "de fautes"
"de faits" » "des faits", "de fait", "les faits"

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 facts") OR ("de faits"))) OR ((("de factsr") OR ("mode factor")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"de facts\") OR (\"de faits\"))) or (((\"de factsr\") or (\"mode factor\"))))".
• Removing quotes may allow a broader search: (((( de facts ) OR ( de faits ))) or ((( de factsr ) or ( mode factor )))).
• Adding a wildcard symbol may retrieve word variants: (((("de facts") OR ("de faits"))) or ((("de factsr") or ("mode factor"))))*.
