Mapsearch is a CKAN-extension to add a scale-aware, map-centered search to the CKAN spatial extension (ckanext-spatial). Its main distinguishing factor is the scale-awareness of the search-engine. This scale-awareness lets you see how many results there are on 5 different scales for the same geographic area of interest, by using an extra area field during indexing. The extension requires Solr >= 3.1 with solr-spatial-field backend. The search-backend of the spatial extension must be set to ‘solr-spatial-field’. Installation requires adding a spatial_area field to the Solr schema.xml file. Development was partially funded by Filas under POR FESR Lazio 2007-2013.
