It's possible this will be brought back as a GA feature - but it took a lot of server power and really slowed things down.

Unfortunately it wasn't just causing problems for people getting lag, but if someone with a massive account did one of those searches it would basically put everyone else in a queue to find it out.

We've got better systems in place now for caching and fetching that kind of data, so it's more possible than before :)
