Perhaps you should try some spelling variations:
"mode factor" » "model factor", "models factor", "model factory", "moe factor", "modose factor", "mode factores", "mode falcoor", "mode faconor", "mode factsr"
"mode factr" » "model factor", "modes factor", "model facts", "moe factr", "mode falcor", "mode faconr"
"de factor" » "e factor", "dose factor", "de factores", "de falcoor", "de faconor", "de factsr"
"de faitor" » "de fair", "de faits", "de fato", "de faitsor", "le faitor", "se faitor"
"de facto" » "e facto", "de falcoo", "de facono", "de facts"
"de fact" » "e fact", "de falco", "de facon"
"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 ("de faitor"))) OR ((("mode factor") OR ("mode factr"))))) OR ((("de facto") OR ("de fact"))))) OR ("de fait")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"de factor\") or (\"de faitor\"))) or (((\"mode factor\") or (\"mode factr\"))))) or (((\"de facto\") OR (\"de fact\"))))) or (\"de fait\"))".
• Removing quotes may allow a broader search: (((((((( de factor ) or ( de faitor ))) or ((( mode factor ) or ( mode factr ))))) or ((( de facto ) OR ( de fact ))))) or ( de fait )).
• Adding a wildcard symbol may retrieve word variants: (((((((("de factor") or ("de faitor"))) or ((("mode factor") or ("mode factr"))))) or ((("de facto") OR ("de fact"))))) or ("de fait"))*.
