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