My sphere is the other end: Product pages with relatively thin content. Hardly any phrase related to the term "widget" will be likely to occur on the page at all.

So if you have a bunch of different "good phrases" on a page, but the page does not contain some of the other words and phrases that the "good phrase" is indicative of, a filter catches it.

Which definitely is not the case on most of my product pages. Nevertheless my pages still do fine in the SERPS (though I admit its a niche market). So all in all evidence, that at least the spam detection patent is quite likely to be applied to only a strongly selected set of phrases. Which is only natural: It is limited to spammy phrases.

But for me the question remains open, to what extent phrase-based IR can be applied to such an enormous amount of words and their possible combinations in an environment like the internet.
