+== Overview ==
+
+Actually GeoNetwork only handle bbox search using Lucene
+
+In a metadata record you could define an extent using
+
+    * a description
+    * a bbox in latlong
+    * or a gml object 
+
+In the search interface, we could search using a geographic keyword (matched to description in the metadata) or bbox matched to bbox in metadata
+
+Requirements:
+    * handle geographic search between user search criteria (which could be description (eg. canton, commune), bbox, geomtries and metadata records extent information

+
+----
+
+== Motivations ==
+Improve spatial search support in GeoNetwork.
+
+== Proposal == 
+On indexing procedure, populate a spatial index based on Shapefile. Store the shapefile index in memory to run the spatial filter after the search.
+
+The following operations are supported :
+ * ENCLOSES
+ * CROSSES,
+ * OUTSIDEOF,
+ * EQUAL,
+ * INTERSECTION,
+ * OVERLAPS,
+ * TOUCHES,
+ * WITHIN,
+
+Query Examples :
+ * http://localhost:8080/geonetwork/srv/en/xml.search?geometry=POLYGON((10%2010,10%2020,20%2020,20%2015,10%2010))&relation=intersection
