Disclosed herein are systems, methods, and software for facilitating enhanced search services. In an implementation, an enhanced search service receives a search query associated with a user and responsively identifies documents relevant to the search query. The enhanced search service also identifies a social label for each of the documents that is at least partly representative of how the document relates socially to the user. The enhanced search service replies to the search query with search results indicative of at least the documents and the social label for each of the documents.
