Method Detail

buildSpatialQueryByQuadTree

public static Query buildSpatialQueryByQuadTree(double latitude,
                                double longitude,
                                double radius,
                                String fieldName)

Returns a Lucene Query which relies on Hibernate Search Spatial quad tree indexation to find candidate documents and filter its results in radius range by a DistanceFilter

Parameters:

latitude - WGS84 latitude of the center of the search

longitude - WGS84 longitude of the center of the search

radius - distance max to center in km

fieldName - name of the Lucene Field implementing Coordinates

Returns:

Lucene Query to be used in a search

                             String fieldName)

Returns a Lucene Query which relies on Hibernate Search Spatial quad tree indexation to filter document at radius and filter its results by a fine DistanceFilter

Parameters:

latitude - WGS84 latitude of the center of the search

longitude - WGS84 longitude of the center of the search

radius - distance max to center in km

fieldName - name of the Lucene Field implementing Coordinates
