1. A method comprising, by one or more computing devices: receiving, from a client device of a first user, a query corresponding to a first node type of a plurality of node types; searching one or more search indices to identify one or more nodes of a social graph matching the query, wherein the search indices maintain an index of a plurality of nodes of the first node type, each node of the plurality of nodes having a static rank which is based at least in part on a pre-calculated value for each node, wherein the value is calculated based on one or more sub-values corresponding to one or more factors, respectively, wherein the factors comprise a number of edges of a particular edge type that are connected to the node or attributes of edges connected to the node; and sending, to the client device of the first user for display, a search-results interface responsive to the received query, the search-results interface comprising reference to one or more nodes each corresponding to the first node type and having a static rank greater than a threshold rank.
