Perhaps you should try some spelling variations:
"mode factor" » "model factor", "models factor", "model factory", "mod_ factor", "moda factor", "mod3 factor"
"23 factor" » "2.3 factor", "23 factors", "23 factory"
"da facto" » "de facto", "a factor", "5 facto"
"e fact" » "_ fact", "a fact", "3 fact"

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: (((("mode factor") OR ((((("da facto") OR ("23 factor"))) OR ("da facto"))))) OR ("e fact")).
• Removing quotes may allow a broader search: (((( mode factor ) or ((((( da facto ) or ( 23 factor ))) or ( da facto ))))) or ( e fact )).
• Adding a wildcard symbol may retrieve word variants: (((("mode factor") or ((((("da facto") or ("23 factor"))) or ("da facto"))))) or ("e fact"))*.
