Embodiments include methods, apparatus, and systems for using range queries in multidimensional data in a database. One embodiment is a method that defines a query box from a search for multidimensional data in a database. The method examines an intersection between a Z-interval and the query box by decomposing the Z-interval into hyper-boxes that are also Z-intervals in Z space. Items in the query box that match the search are discovered.
