Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage medium, to facilitate searching indexed resources associated with sort key values. In one aspect, a method includes actions of maintaining an index including a respective index entry for each of multiple resources, wherein each index entry includes a first sort key that is associated with a corresponding sort key value, receiving a query from a user device, obtaining, based on query features, a first restrict criterion that includes one or more binary value bits, determining, based on (i) the first restrict criterion and (ii) the first sort key, a first count of index entries that are each associated with a respective resource that is responsive to the query, and in response to determining that the first count of index entries satisfies the predetermined threshold, obtaining a set of index entries corresponding to resources related to the query.
