Abstract
A method and apparatus for performing an accelerated radius search. A search category is built having a density value corresponding to a geographic area. A first search radius is generated based upon the category, and the first search radius is used to perform a first search. If the first search returns an insufficient number of results, a second search radius is generated by using an heuristic to increase the first search radius, and the second search radius is used to perform a second search. The search is repeated until a desired results set is returned.
