Perhaps you should try some spelling variations:
"mode factor" » "model factor", "models factor", "model factory", "mode factors", "modone factor", "modage factor", "mode factr", "mode factsr"
"de factors" » "de factores", "e factors", "3e factors", "de factorss", "done factors", "dage factors", "de factrs", "de factsrs"
"de faitor" » "de fair", "de faits", "de fato", "de faitsor", "le faitor", "se faitor"
"e factor" » "e factors", "one factor", "age factor", "e factr", "e factsr"
"de fait" » "de faits", "le fait", "se fait"
"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 factors") OR ("e factor"))) OR ("de faitor"))) OR ("mode factor"))) OR ("de facto"))) OR ("de fait")).
• Removing quotes may allow a broader search: (((((((((( de factors ) or ( e factor ))) or ( de faitor ))) or ( mode factor ))) or ( de facto ))) or ( de fait )).
• Adding a wildcard symbol may retrieve word variants: (((((((((("de factors") or ("e factor"))) or ("de faitor"))) or ("mode factor"))) or ("de facto"))) or ("de fait"))*.
