This paper presents a novel approach that transforms the feature space into a new feature space such that a range query in the original space is mapped into an equivalent box query in the transformed space. Since box queries are axis aligned, there are several implementational advantages that can be exploited to speed up the retrieval of query results using R-Tree  like indexing schemes. For two dimensional data, the transformation is precise. For larger than two dimensions, we propose adoi:10.1109/tkde.2014.2363658 fatcat:zjy3lnb3czfo3movgechueryfi
