Perhaps you should try some spelling variations:
"dose factor" » "noise factor", "one factor", "mode factor", "dose factsr"
"de facteur" » "de facteurs", "le facteur", "du facteur", "de faiteur", "e facteur", "de falcoeur"
"de faito" » "de fait", "de faits", "de fato"
"de factoor" » "de faitoor", "e factoor", "de falcooor", "de factsor"
"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: (((((((("de factoor") OR ("de facteur"))) OR ("dose factor"))) OR ((("de faito") OR ("de facto"))))) OR ("de fact")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"de factoor\") or (\"de facteur\"))) or (\"dose factor\"))) or (((\"de faito\") OR (\"de facto\"))))) or (\"de fact\"))".
• Removing quotes may allow a broader search: (((((((( de factoor ) or ( de facteur ))) or ( dose factor ))) or ((( de faito ) OR ( de facto ))))) or ( de fact )).
• Adding a wildcard symbol may retrieve word variants: (((((((("de factoor") or ("de facteur"))) or ("dose factor"))) or ((("de faito") OR ("de facto"))))) or ("de fact"))*.
