In this paper, the authors deal with the problem of searching top-products in e-shops according to user preferences. In the era of huge datasets, the top-search becomes an effective way to decrease the search time of top-objects. Since they suppose locally accessible data only, the multidimensional indexes containing all attributes together seem to be more effective than a distribution of each attribute to a separate index. Therefore they introduce the top-search algorithm over grid file - the multidimensional index not used for the top-search yet.
