Yahoo Search Using Gears ?

The web is discussing about the new yahoo home page for last two days and I also thought of visiting the same.Accidentally I used yahoo search in Chrome and found that it is asking for that familiar message from Google Gear .I wanted to check when it was introduced and how it can be used in offline mode.But I did not find much information about this and found that other people are also asking the same question.


Can any one provide more information about this?
