Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor", "dos_ factor", "dosa factor", "dos5 factor"
"de factor" » "de facto", "e factor", "mode factor", "de factoor", "de falcoor", "one factor", "d_ factor", "da factor", "d5 factor"
"de falcoo" » "de falco", "die falcon", "de facto"
"de facon" » "de facto", "de falco", "la facon"
"de fact" » "de facto", "de falco", "one fact", "d_ fact", "da fact", "d5 fact"
"de fait" » "de faits", "le fait", "se fait"
"e fact" » "_ fact", "a fact", "5 fact"
"3 fact" » "3 facts", "3 fast", "3 factor"

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 ("dose factor"))) OR ("de falcoo"))) OR ("de facon"))) OR ((((("de fact") OR ("de fait"))) OR ((("e fact") OR ((("3 fact") OR ("3 face")))))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"de factor\") OR (\"dose factor\"))) or (\"de falcoo\"))) or (\"de facon\"))) or (((((\"de fact\") or (\"de fait\"))) or (((\"e fact\") or (((\"3 fact\") or (\"3 face\"))))))))".
• Removing quotes may allow a broader search: (((((((( de factor ) OR ( dose factor ))) or ( de falcoo ))) or ( de facon ))) or ((((( de fact ) or ( de fait ))) or ((( e fact ) or ((( 3 fact ) or ( 3 face )))))))).
• Adding a wildcard symbol may retrieve word variants: (((((((("de factor") OR ("dose factor"))) or ("de falcoo"))) or ("de facon"))) or ((((("de fact") or ("de fait"))) or ((("e fact") or ((("3 fact") or ("3 face"))))))))*.
