DN research: How do you interpret overture?

[SEO Montreal]

i found
porn keyword1 keyword.net had 138 searches
pornkeyword1keyword.net had 0

is that just a mistake? does it mean people are actually typing two words plus a word with the extensions attached?

How good a predictor of traffic is porn keyword keyword.net for the associated DN?

Thanks for the help (I'll be adding rep for good answers).

I personally would put overture a side and try a service like keyworddiscovery.com they are much more dependable and their results are not modified
