    retrieving, by the one or more computing devices, one or more second users of the social-networking system that match the query from the first user, the one or more second users corresponding to one or more second nodes of the graph, respectively, each retrieved second user having a visibility setting specifying a threshold degree of separation, the visibility setting of each second user specifying which other users of the social-networking system can view information from the social-networking system associated with the second user based on the other user'"'"'s degree of separation from the second user;

    determining, by the one or more computing devices, for each of the second users, the degree of separation between the first node corresponding to the first user and the second node corresponding to the second user; and

    providing, by the one or more computing devices, information associated with each second user corresponding to a second node having a degree of separation less than or equal to the threshold degree of separation specified in the visibility setting of the second user for display to the first user in response to the query.
