Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "mode factor", "moore factor", "dose factorr", "dosex factor", "dose factr"
"de factor" » "e factor", "mode factor", "de factores", "de factorr", "dex factor", "de factr", "de faitor", "de falcoor"
"one factor" » "one factorr", "onex factor", "one 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: (((((("de factor") OR ((("dose factor") OR ("one factor"))))) OR ((("de facto") OR ("e facto"))))) OR ("de fact")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"de factor\") or (((\"dose factor\") OR (\"one factor\"))))) or (((\"de facto\") or (\"e facto\"))))) or (\"de fact\"))".
• Removing quotes may allow a broader search: (((((( de factor ) or ((( dose factor ) OR ( one factor ))))) or ((( de facto ) or ( e facto ))))) or ( de fact )).
• Adding a wildcard symbol may retrieve word variants: (((((("de factor") or ((("dose factor") OR ("one factor"))))) or ((("de facto") or ("e facto"))))) or ("de fact"))*.
