Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "moore factor"
"mode factor" » "model factor", "models factor", "model factory", "mode factoor", "mode faitor", "moe factor"
"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 falcoo") OR ("de fact"))) OR ((("mode factor") OR ("dose factor")))).
• Removing quotes may allow a broader search: (((( de falcoo ) or ( de fact ))) or ((( mode factor ) or ( dose factor )))).
• Adding a wildcard symbol may retrieve word variants: (((("de falcoo") or ("de fact"))) or ((("mode factor") or ("dose factor"))))*.
