Perhaps you should try some spelling variations:
"e factsr" » "e factor", "e factors", "e factory"
"de fact" » "de facto", "e fact", "de falco"
"de fait" » "de faits", "le fait", "se fait"
"one factor" » "onde factor", "one factorr", "onex factor", "one factors"
"e facto" » "de facto", "e factor", "ex facto"

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