Abstract: A social collaboration search tool provides a mechanism for collaborators within an organization to search for and retrieve conversations that include social knowledge interactions. The social collaboration search tool may also provide additional social information to the searcher. The social knowledge interactions search tool can provide a mechanism by which these interactions are indexed and surfaced in a first class search vertical with specialized display formats that may enable the searcher to efficiently retrieve and use the most important or relevant information.
