Yahoo Tests Livesearch On AllTheWeb; Google Patent Problem, Perhaps?
Yahoo’s AllTheWeb service is sporting a new
Livesearch feature. It’s pretty
interesting. As you type into the search box, search results automatically start
appearing. And more interesting, it’s similar to something Google’s already
sought to patent.
Let’s dive into the Livesearch system first. Say you are looking for
information about HD TVs. You type h, and a list of suggested searches appears
to the left of the main search results area, including:
In the search results, you start seeing listings for hotmail, second on the
list. That’s the term AllTheWeb is guessing you might be after. Ah — but we’re
not after hotmail! That’s OK. As soon as you enter another letter, making hd,
In the search results, hdtv is automatically selected as your search query,
giving you results on that topic.
It’ll be fun to see if this takes off more if it moves to regular Yahoo.
Potentially, it will speed up searching, giving you answers faster than you’ve
even completed typing in your search terms.
Certainly it’s nice to see the query refinement given better play than on
Yahoo, making it easier for people to understand there are alternatives and
related terms to their queries. Query refinement has long felt neglected, as
I’ve covered more in my

Refinement, The Human Scale Problem & Creating The Search Dialog posts last
Yahoo explains a bit more about Livesearch in its blog post,
AlltheWeb, plus they give some feedback options there. Meanwhile, a revisit
to some things that Livesearch is similar to:
Just to stress, none of the services above goes the extra step of actually
showing results automatically, in addition to suggested search terms, as
Livesearch does. I do feel like I’ve seen someone do this combo move before, but
I can’t think of any offhand or after doing some searching. Those closest thing
is how Google
will prefetch the first result in a listed for a query for those using
Firefox, as a means of speeding up access to pages. But that’s a different
Closer to the mark, Bill Slawski’s very detailed
Can Google Read Your Mind? Processing
Predictive Queries article talks about a Google patent application on a
system that seems very close to what Yahoo’s Livesearch is doing. Bill might pop
in here to postscript some thoughts on how this applies to what Yahoo’s doing.
Certainly Livesearch demonstrates one thing — how quickly search engines can
generate results, or more correctly, how many results they already have cached
and ready to serve up without having to “hit disk” to actually do a search.
In other words, when so many people are constantly searching for things like
“hdtv,” search engines don’t have to always go back and search through billions
of pages for the results. They can simply pull up the same results they already
served recently from fast memory, a
for being speedy.
It’s also nice to see AllTheWeb finally used for something again, I suppose.
Back when Overture bought it, it was
as sort of a alpha testing platform with AltaVista a more consumer friendly beta
site. Then Yahoo
Overture, pretty much throwing both AllTheWeb and AltaVista into abandonment.
I do see a number of similarities between Live Search and Google Suggest, but there are differences, too. I’m excited to see AllTheWeb being used in this manner.
I did look back at some of the Yahoo! patents and patent applications to see if I could find something similar to what Yahoo! is doing in this Livesearch. I did come up with something close in a patent application that is part of a larger set of refinements to a search user interface in Universal search interface systems and methods. There, we’re told that:
The present invention provides highly sophisticated query completion features. As a user types, related words and units are shown (could appear in a drop-down box). These could be based on related searches but personalized to an individual user. For example, when user types in “sf”, a drop-box showing weather, hotels, restaurants, etc. may be shown based, in part, on what this user has searched for in the past about “sf”.
This patent application was filed April 5, 2004 and published December 9, 2004, earlier than Google’s Anticipated query generation and processing in a search engine. But it covers a wider range of enhancements to a search interface. It will be interesting if some of the other concepts discussed in the Yahoo! patent application make their way into livesearch. — Bill Slawski
Postscript 2 From Danny: I did ask Yahoo about the patent issue, but they said they couldn’t comment on legal issues.
