How does find/filter on kinsky and upnp in general work?

[KoS]

Hi Simon

do you know how the filter/search function on upnp works? e.g. in kinsky you can "filter" the albums:
- does the kinsky app retrieve the whole list and than filter it itself
- or does it send the upnp the filter string and then retrieves only the items that its looking for?
