Unfortunately, this not really in the cards right now. The silverbullet server is pretty “dumb” — all it does is serve and persist files on disk. All the interesting logic: the indexing, the querying happens 100% in the client (the browser). In a previous version (v1) it actually happened both on the server and client, but for simplification reasons I now moved everything to just the browser, which means that accessing this functionality from the CLI is pretty much not doable.
