1. A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to: generate an indexed set of geometry objects in a graph database, each geometry object in the indexed set of geometry objects identified by a geohash representing a unique coordinate pair of the geometry object identifying a unique geographical location on the Earth, wherein the indexed set of geometry objects is generated by generating a hashmap index of the set of received geometry objects; receive a geomap query to identify a number K-closest geometry objects from the indexed set of geometry objects in the graph database within a distance D to a geo-location L, the geo-location L identified by a unique coordinate pair of the geo-location L identifying a geographical location on Earth; compute a geohash for the geo-location L; identify a subset of geometry objects from the indexed set of geometry objects in the graph database having a number of prefix bits in the respective geohash in common with a number of bits NB in the prefix of the geohash of the geo-location L; identify K-closest geometry objects from the subset of geometry objects that are closest to the geo-location L, wherein the K-closest geometry objects are identified by the computer readable program further causing the computing device to: for each geometry object in the set of indexed geometry objects, compute a distance between a location of the geometry object represented by the geohash associated with the geometry object and the geo-location L represented by the geohash associated with the geo-location L thereby forming a computed distance, wherein determining the computed distance using geohashes results in improved retrieval of spatial information; determine whether the computed distance between the location of the geometry object and the geo-location L is less than or equal to the distance D; responsive to the computed distance between the location of the geometry object and the geo-location L being less than or equal to the distance D, add the geometry object to a set of final results (FR) along with the computed distance between the location of the geometry object and the geo-location L; and identify the K-closest geometry objects from the set of final results (FR) based on the computed distance between the location of the geometry object and the geo-location L; and return the K-closest geometry objects to a user who submitted the geomap query.
