Hi Neophytos,
I believe that the problem is that is not package aware. For example file-storage is a CR app and so is CMS. A search on file-storage will yield results from CMS, the same goes with News. Not really sure if this an OpenFTS problem or the service contract may need more parameters. I believe Rob Locke can furthere elaborate on this behaviour of search. I have been working with modetp with some collaboration with Luke P, so I am dont really know the guts of News module.
