Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor", "dosde factor", "dose factorr", "dosex factor"
"ex factor" » "sex factor", "x factor", "ix factor"
"de falcoo" » "de falco", "die falcon", "de facto"
"e facto" » "de facto", "e factor", "ex 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: (((((("ex factor") OR ("dose factor"))) OR ((("de falcoo") OR ("e facto"))))) OR ("de fact")).
• Removing quotes may allow a broader search: (((((( ex factor ) or ( dose factor ))) or ((( de falcoo ) or ( e facto ))))) or ( de fact )).
• Adding a wildcard symbol may retrieve word variants: (((((("ex factor") or ("dose factor"))) or ((("de falcoo") or ("e facto"))))) or ("de fact"))*.
