The social search from Google is a new phenomenon and it is very much helpful to the user who is very much interested in searching some content or contact from his social circle. The basic idea behind it is that the content from a known contact can be more relevant than the content provided by a stranger. You can read a movie review written by an expert, but if you get the review from your best friend, obviously it will be more convincing for you.
After you get signed into Google, you can see social search results for different searches. It is located at the bottom of the page under the heading “results from people in your social circle.” Social search will make your search more personalized. It will show any article or comments made by any of your contacts on the subject which you are searching in Google.
People in your social circle can come from a wide variety of sources. It can be from your Gtalk chat list or your friends or family or coworkers in the Google contacts. You can have a large list of contacts through other social networking sites like FriendFeed or Twitter. You can also include contacts from your Google Buzz stream. You can also get the people you are following in Google Reader and Google Buzz. You may have got a friend in twitter whom in turn has got 50 contacts there. You will be surprised to know that those 50 people will also be added in your contact list. These connections will be known as your secondary connections and the people whom you know personally will be referred as your direct connections. You can get the details of these in your social circle page.
