Abstract

Search results may be sorted or filtered based on scores assigned to the search results. For example, scores may be assigned to search results based on characteristics of surrogate representations of the search results, which are relatively short summaries or excerpts of the search result that may be presented in place of the search results themselves, and those assigned scores may be used to sort or filter the search results. In one example, pairs of search results may be examined to identify significant drops in quality between search results, which is indicated by a large relative or absolute difference in the scores of the search results. Search results with scores that indicate ranks that are lower than a lower ranked search result of the pair of search results may be eliminated when the difference between the scores assigned to the pair of search results exceeds a maximum allowable difference.
