Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor", "dose factorr", "dosex factor", "dos5 factor", "dos_ factor", "dosa factor", "dos3 factor"
"de facto" » "de factor", "dex facto", "d5 facto", "de faito", "de falcoo", "de facono", "d_ facto", "da facto", "d3 facto"
"e facto" » "e factor", "ex facto", "5 facto", "_ facto", "a facto", "3 facto"
"de fact" » "de fait", "de falco", "de facon", "d_ fact", "da fact", "d3 fact"
"e fact" » "_ fact", "a fact", "3 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: (("dose factor") OR ((((("de facto") OR ("e facto"))) OR ((("de fact") OR ("e fact")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"dose factor\") or (((((\"de facto\") or (\"e facto\"))) or (((\"de fact\") OR (\"e fact\"))))))".
• Removing quotes may allow a broader search: (( dose factor ) or ((((( de facto ) or ( e facto ))) or ((( de fact ) OR ( e fact )))))).
• Adding a wildcard symbol may retrieve word variants: (("dose factor") or ((((("de facto") or ("e facto"))) or ((("de fact") OR ("e fact"))))))*.
