You can store indexes and caches wherever you like, you could for instance store them on a DVD, as long as Zilverline (and your webserver) can access them.

If you supply a url with your collection, the search results will map to the url instead of the source. This allows you to retrieve your result hits from your webserver, instead of disk.

Zilverline is internationalized (English, French, German, Brazil, Spanish and Dutch), and has support for skins (now three).
