9. One or more computer storage media configured to store instructions that are executable by one or more processing devices to perform operations comprising: accessing clusters, with two or more clusters corresponding to different name contexts, and with a cluster comprising resources that are determined to be relevant to a name context of the cluster; receiving, for a resource in the cluster, a search score for the resource, the search score being indicative of a relevance of the resource to a search query that includes the name context of the cluster; receiving, for the resource in the cluster, a resource ranking score for the resource in the cluster, the resource ranking score being (i) at least partly based on a cluster relation score, and (ii) indicative of a ranking of the resource in the cluster relative to rankings of other resources in the cluster; wherein the cluster relation score is indicative of an authority of the resource relative to authorities of the other resources in the cluster; generating a cluster rank score for the cluster, the cluster rank score at least partly based on the search scores for the resources and the resource ranking scores for the resources; and ranking the clusters according to their cluster rank score.

The one or more computer storage media of claim 9 , wherein generating the cluster rank score comprises: applying a linear weighted regression to the search scores for the resources in the cluster and to the resource ranking scores for the resources in the cluster, wherein the linear weighted regression comprises an additive function in which (a) one or more of the search scores are multiplied by one or more first weights, (b) one or more of the resource ranking scores are multiplied by one or more second weight values, and (c) a value of the one or more of the search scores multiplied by one or more first weights is added to a value of the one or more of the resource ranking scores multiplied by one or more second weight values.
