UNIVERSAL QUERY SEARCH RESULTS

摘要

Generally described, embodiments of the present invention provide the ability to generate a universal query result set from several different search index result sets by including identifications of items from the different search index result sets in an accurate manner. After a query has been submitted, search index result sets are received from several different search indexes, an allocation score for each search index is computed and a universal item score for the top-level item identified in each search index is computed. The method then combines the allocation score and the universal item score for the top level item for each search index result set and adds the item with the highest combined score to the universal query result set.

1. A computer-implemented method, comprising:
under control of one or more computer systems configured with executable instructions,
distributing a query to a plurality of search indexes, each search index corresponding to a category of items;receiving a plurality of search index result sets;determining probabilities of items in the plurality of search index result sets satisfying the query;normalizing at least one of a plurality of distinct internal ranking scales associated with the plurality of search indexes to a common ranking scale; andgenerating a universal query result set including at least a plurality of the items selected from the plurality of search index result sets in an order utilizing the common ranking scale based at least in part on the probabilities of the items satisfying the query.
