Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor"
"de factor" » "de facto", "e factor", "mode factor", "de factoor", "de faitor"
"de faitor" » "de facto", "de fair", "de fait"
"de falcoo" » "de falco", "die falcon", "de facto"
"de fact" » "de facto", "de fait", "e fact"

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 ("dose factor"))) OR ("de falcoo"))) OR ("de fact")).
• Removing quotes may allow a broader search: (((((((( de factor ) or ( de faitor ))) or ( dose factor ))) or ( de falcoo ))) or ( de fact )).
• Adding a wildcard symbol may retrieve word variants: (((((((("de factor") or ("de faitor"))) or ("dose factor"))) or ("de falcoo"))) or ("de fact"))*.
