How would you interpret these results? -- (re: rankings problems)

For awhile I have thought I was being filtered out for a penguin "penalty" because almost none of my internal pages can be found for their relevant search terms anywhere in the top 100+
But I was just checking on something and, as usual, when I searched for "kw one" (two word phrase) I'm nowhere to be found but when I searched for "kw one followed by four words" (six word phrase as it appears on my page) then that same internal page ranks #1, as you would expect normally. But I would NOT expect to see this if the page was being affected by penguin?

This was a surprising discovery for me because I have been working hard for the last two months to get this site ranking again with almost no improvement at all (though it was originally hit over a year ago, I only recently was able to get back to work on it).

I'm just curious to hear how others here would interpret these results if you saw them?
Thanks!

Penguin is not a site wide penalty, it target certain keywords only. Did you build any links using the 6 word phrase?

It's still possible that your other keyword phrases have been affected by Penguin.

I would suggest to do a 301 redirect to your new domain name, so all your link juice will flow to your new site.
Starting a fresh new domain name is better option rather than try to fix your penalized site.
