Lobby list limit

Apparently there’s a limit to how many lobbies load in the list for any given raid, and changing stage filter doesn’t affect it. So if there’s a billion lobbies for valtan and only 5 inferno, then changing difficulty to inferno might result in no lobbies showing up at all. If I type anything like “G2” in search then I get some results but I basically have to guess what people would put in their title…
