SYSTEMS AND METHODS FOR INDEXING AND SEARCHING DATA RECORDS BASED ON DISTANCE METRICS

摘要

A computer implemented method for searching a data structure is disclosed. A first node on the data structure is examined. A determination is made as to whether the first node is associated with one or more child nodes. When the first node not associated with one or more child nodes, elements within the first node that are located within a defined distance away from a defined location rendered on the first node are identified. The identified elements are stored in a data set. The nodal radius cut-off value is updated if the value is less than a difference of one half a radius of the first node and a distance from the defined location to the center point of the first node. The first node is labeled to indicate that the node has been examined.
