Perhaps you should try some spelling variations:
"mode factor" » "model factor", "models factor", "model factory", "mode factorr", "modex factor", "mode factr"
"de facto" » "de factor", "dex facto", "de fact"
"e facto" » "e factor", "ex facto", "e fact"
"de fait" » "de faits", "le fait", "se fait"

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 facto") OR ("e facto"))) OR ("de fait"))) OR ("mode factor")).
• Removing quotes may allow a broader search: (((((( de facto ) or ( e facto ))) or ( de fait ))) or ( mode factor )).
• Adding a wildcard symbol may retrieve word variants: (((((("de facto") or ("e facto"))) or ("de fait"))) or ("mode factor"))*.
