Perhaps you should try some spelling variations:
"mode factor" » "model factor", "models factor", "model factory", "modose factor", "mode factores", "mode factorij", "mode factors", "modone factor", "modage factor", "mode factr", "mode factsr"
"de factor" » "dose factor", "de factores", "de factorij", "de factors", "done factor", "dage factor", "de factr", "de factsr"
"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 factor") OR ("e factor"))) OR ("de faitor"))) OR ("mode factor"))) OR ("de facto"))) OR ("de fait")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((((\"de factor\") OR (\"e factor\"))) or (\"de faitor\"))) or (\"mode factor\"))) or (\"de facto\"))) or (\"de fait\"))".
• Removing quotes may allow a broader search: (((((((((( de factor ) OR ( e factor ))) or ( de faitor ))) or ( mode factor ))) or ( de facto ))) or ( de fait )).
• Adding a wildcard symbol may retrieve word variants: (((((((((("de factor") OR ("e factor"))) or ("de faitor"))) or ("mode factor"))) or ("de facto"))) or ("de fait"))*.
