Some orkut profiles will appear in Google search results as an orkut OneBox. A OneBox is a summary of your orkut profile, including key details like your name, photo and location. A OneBox appears only when someone who is logged in to orkut performs a search on Google.com for their friends or friends of friends. Keep in mind that this project is still in its experimental stage, so for now, only a small percentage of orkut users will see the OneBox in their search results.
Wondering what a OneBox Is ??
On top of the organic results (and sometimes at the bottom), Google shows OneBox results for queries that can be answered instantly or when a direct link can be offered.
You'll have the same privacy settings for the OneBox as you do for your full orkut profile, so no information you've made private in orkut will appear in Google search results. Additionally, if you wish to opt-out of the orkut Onebox altogether, you can do so by following these steps:
On the left sidebar of the orkut hompage, click settings. Under orkut in Google search results, click the hide information bubble.
Click save changes at the bottom of the page.

Note:
Orkut and the search team both don't have a way to change whose profiles will appear in Google search results as a OneBox.
