Can't search NAS or other Live

Have a Live and Live Plus along with a D-Link DNS-323 NAS. No problems in seeing the folders and streams between each other, from the PC’s HD and the NAS but can’t search.

Can search the USB drives if directly connected but nothing through the network. What do I need to do to get the search working?

The media library can only be compiled for local storage.

No media library, no search.

" Media Library Compilation
Media Library Compilation refers to the process of scanning and consolidating the
media contents of a USB drive into one comprehensive database so that you can
easily browse and locate media files based on certain metadata information
(e.g., video files are categorized based on title or release date)."
