Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor", "dos_ factor", "dosa factor", "dos3 factor", "dose factsr"
"de factr" » "de facteur", "de fazer", "de facon", "d_ factr", "da factr", "d3 factr"
"de fait" » "de faits", "le fait", "se fait"
"e fact" » "_ fact", "a fact", "3 fact"
"de facto" » "d_ facto", "da facto", "d3 facto", "de facts"

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: (((((("e fact") OR ("de falco"))) OR ("de fait"))) OR ((("dose factor") OR ((((("de factr") OR ("de facto"))) OR ("dose factor")))))).
• Removing quotes may allow a broader search: (((((( e fact ) or ( de falco ))) or ( de fait ))) or ((( dose factor ) or ((((( de factr ) or ( de facto ))) or ( dose factor )))))).
• Adding a wildcard symbol may retrieve word variants: (((((("e fact") or ("de falco"))) or ("de fait"))) or ((("dose factor") or ((((("de factr") or ("de facto"))) or ("dose factor"))))))*.
