This is taken from the Google Search Tips. Until recently it said quite the reverse. That's a pretty fundamental change to bring in without a fanfare! :glasses:
Google now uses stemming technology. Thus, when appropriate, it will search not only for your search terms, but also for words that are similar to some or all of those terms. If you search for "pet lemur dietary needs", Google will also search for "pet lemur diet needs", and other related variations of your terms. Any variants of your terms that were searched for will be highlighted in the snippet of text accompanying each result.
Google is stemming now

Previously a page optimised for the phrase "online gambling' (purely for an example) was competing with pages that also ranked well for that term. Now a page optimised for "online gambling" is also competing against pages optimised for "gamble online" and maybe even "online betting", "bet online" etc, etc.
That's a massive change for SEO to take on. It will have both positive and negative effects for us. For Instance: it may allow a site that dominates the SERPs for popular phrases to automatically have the same dominence over less popular phrases without any additional work. Whether that is good or bad will depend on whether that dominating site is our own, or a competitor we hoped to 'out-niche'.
The LocalRank filter also seems to have come into effect without any great fanfare, and while we suspect it has been in the general algo mix for a while, it seems to be more notable since this big shift in algo and filtering.
In fact, it could be that we are not seeing a single change (which many are going mad trying to decode and assign motive to) but rather a whole mess of smaller independantly motivated changes that have simply coincided and thus made it far harder to see what has changed and why.

ROFLMAO LOL LOLYes, but they work for Google The rest of us hypothesise....

Peter, your sarcasm and ability to cut through the BS is BRILIANT!!! Are you sure you aren't Australian?

So my theory is: there is no filter, just badly implemented stemming.
How does that account for my wife's site (http://book-cover-design.com) going from #1 to nowhere for the term "book cover design"? She still has good page rank and still shows up #1 if you override the filter.

I'm amazed the site was ever number one. The home page is all images even for the title "book cover design", the contact info and the links - the phrase book cover design only appears in the title, description and keywords never in the visible text. There's a few inbound links showing mostly from your site.
For a filtered search The links page is the first to show. The DMOZ and Google directories list it without the www.
I think you'd be better off adding some text and doing some optimization on the page before you complain about google. :evil:

but this might indicate that a major factor in the update is that much less power given to keywords in URL.
which is of course obviously done for seo if its multiple keywords, without seo you would probably have gone with archer design as the description would tell the public what the site is about and the title would be used for branding.

I've seen other people suggest that but in the last couple of days I have started to suspect the opposite. I've seen some very mediocre sites from a traditional SEO point of view come up #1 and the only possible explanation seems to be the KWs in the URL.
but this might indicate that a major factor in the update is that much less power given to keywords in URL
Check out this search for instance. <http://www.google.co...line pharmacy>.
Look at the sites at #3 & #4. BTW number 3 was at number one yesterday so adjustments are still going on.
<added Dec 1.> The site that was in #3 when I posted the above has now returned to #1 position. I believe that a careful examination of the information available at Scroogle will reveal exactly why this site has survived the shake up and the filters.<end of edit>

We all know now that you can use the advanced search "-junkword" and get virtually the same results for you keywords as existed before all the machinations.
However I have never heard anybody talk about the impact of doing searches enclosed in "". I have found that for some -- not all -- of the keyword phrase that have disappeared this search will restore the site to approximately it's former ranking.
Does anybody have any theories or explanation for this phenomenon?

My guess is that if you have not been penalized by the Florida update, then your web pages may appear on more SERP's for stemmed versions of your important keywords. In turn that is likely to lead to slightly more traffic.
Has anyone else noticed this phenomenon?

Note the one site with three listings on the first page. Then start clicking to the next pages.
Google must be proud. While this doesn't prove stemming, it does show exact phrase matching. Only if you're an "authority", I guess.
Er, back to the topic at hand.

Well it isn't quite true. What Google is doing is much more clever than stemming but it isn't stemming.
Word Variations (Stemming)
Google now uses stemming technology. Thus, when appropriate, it will search not only for your search terms, but also for words that are similar to some or all of those terms.
In what follows, I am assuming that the highlighting feature on the Google Toolbar correctly identifies how Google is treating the words in its Search Algorithm. If Google was really stemming then a search for Friesian Horses would highlight Friesian and Horses in the composite word FriesianHorses. If you have the Google toolbar, you can check it out in this search by clicking on the highlight button.
This shows that Google found the word Friesian in Friesian-Horses, in Friesian_Horses and even in Friesian+Horse. However it didn't find Friesian in the composite FriesianHorses.
So Google I still congratulate you on what you are doing but it isn't really stemming.
