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