Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor", "dose factorr", "dosex factor", "dose factr"
"de facto" » "de factor", "dex facto", "de fact", "de faito", "e facto", "de falcoo"
"e facto" » "e factor", "ex facto", "e fact"
"de fact" » "de fait", "e fact", "de falco"

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