Hello, I'm quite new to WFS and Filtering, so i need an help. I need to filter out some Point Of Interest from my geoserver by these rules: - i need a MAX numbers of POI in a certain area (a BBOX or a radius) - i need to have them sorted by distances, better i need to have only the POI that have the minimum distance from the center of the BBOX or from the center of the radius. Now i know how to filter by area or radius (with BBOX of DWITHIN filtering), i know how to filter a max num of results, but i can't figure out how to obtain only the POI that have the minimum distances. Can anybody help me please? Thanks Marco
