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"
"model facts" » "model factor", "modern facts", "model fast"
"de factor" » "e factor", "dose factor", "de factores", "de falcoor", "de faconor"
"de faitor" » "de fair", "de faits", "de fato", "de faitsor", "le faitor", "se faitor"
"de facto" » "e facto", "de falcoo", "de facono"
"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 ("model facts"))))) 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 ( model facts ))))) 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 ("model facts"))))) or ((("de facto") or ("de fact"))))) or ("de fait"))*.
