My main concern using `{{serverurl}}` is that it won't be available in the lucene index. May be we can consider that it can be customized directly into the `strings.xml` ? 

```
* {{title}} (http://my.geonetwork.catalogue.com/?uuid={{uuid}})
```

Of course, we could also extend the templating syntax so that it would be able to recognize `{{serverurl}}` or some other fields
