Yahoo! has launched what looks to be a very clever search service, targeted for access from mobile devices. It’s called oneSearch and I suspect it’s something that they must have had a pretty smart team putting a truckload of work into designing, developing, and testing. You can find more information about it over at the Yahoo! search blog. Here’s a nutshell description:

With limited bandwidth, screen size and time, this service puts information all right in front of you without having to click on multiple links and then find your way back through a convoluted navigation process, as you might have to do on a more conventional mobile search service.

It’s also interesting to hear that Opera and Yahoo! have shaken hands on a deal to make Yahoo! “the exclusive provider of mobile search” on Opera Mini and Opera Mobile, “across more than 100 countries worldwide”. See the Opera press release and writeup over at webpronews site.
