摘要

A computer comprising a central processing unit (CPU) and a memory coupled to the CPU is provided. The memory includes a vertical index comprising a plurality of vertical index lists. Each vertical index list comprises a head term and a plurality of vertical collection identifiers. Each vertical collection referenced by a vertical collection identifier comprises documents that include the head term. The memory further comprises instructions for receiving a vertical search query from a remote client and instructions for identifying a plurality of candidate vertical collections related to the vertical search query. For each vertical collection in the plurality of candidate vertical collections, there is a vertical search query relevance score associated with the vertical collection. The memory further includes instructions for communicating a name of each candidate collection in the plurality of candidate collections to the remote client together with the search query relevance scores for the candidate collections.
