Abstract
Efficient hierarchical searching is based on object type. By pre-computing additional information and storing it in a fast-lookup structure, it is possible to quickly identify objects that satisfy an object retrieval request. Furthermore, it is also possible to use this technique to avoid object hydration for operations in the store. Moreover, it is possible to leverage database statistical structures such as histograms to estimate the number of qualifying objects without having to examine each object.
