Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor"
"mode factsr" » "mode factor", "model factor", "modes factor", "mode faitsr", "mocbe factsr", "mode fautesr", "moe factsr", "mode falcosr"
"de facts" » "de faits", "cbe facts", "de fautes", "e facts", "de falcos"
"de facto" » "de faito", "e facto", "de falcoo"
"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 ("mode factsr"))) OR ((("de facto") OR ("de facts"))))) OR ("de fact"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"dose factor\") or (\"mode factsr\"))) or (((\"de facto\") OR (\"de facts\"))))) or (\"de fact\"))*".
• Removing quotes may allow a broader search: (((((( dose factor ) or ( mode factsr ))) or ((( de facto ) OR ( de facts ))))) or ( de fact ))*.
