I want to be able to search against a Geonetwork catalog by using the Opensearch protocol.
I already read that Opensearch should be enabled by a file descriptor that is put on this path of the GN instance: http:///geonetwork/srv/eng/portal.opensearch
An example of this document is here. It contains search templates.
- How can i enable Opensearch?
 - How can i customize it?
 - I would also like to know if there's any useful documentation on this matter.
