How does the "Social Section" work under the leads module for Zoho CRM?

Just wondering if anyone can tell me if the Social Section under the leads module in Zoho CRM  auto searches the lead info to associate the social media profiles/pages to it? If so what fields does it search? Is this something that has to be manually entered? 

I am trying to streamline my prospecting process in Zoho CRM and need to reduce some of the fields.  Currently i have fields for facebook, twitter, and other social networks for input.  If this is not necessary and the Social Section attempts to search this information then I can remove those fields. (Redundant information)
