The spatial database allows users to search queries in geographical locations. Most recently, the users search for objects that satisfy a particular constraint. For example, consider a hotel database which contains geographical information about th e hotels and also the list of items (consider as keywords) in which it is famous for. The spatial inverted indexing technique creates an inverted list for each of the keyword and merges the list, thus satisfying the constraint. It then finds the

Moreover, returning a nearest spatial web object that best matches all the keywords is typically hard. The proposed approach retrieves a nearest group of spatial web objects to the query point "q", where the keywords of the objects in the group are aggregated to satisfy the constraint. The approach is efficient if the number of keyword is large. *Reviewed by ICETSET'16 organizing committee
