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