How to search for gems inside of Ruby code, or where did Gem::RemoteInstaller go?

In the Ruby Cookbook recipe 18.1, it is said that

Gem::RemoteInstaller.new.search('rails')

can search for gems on the remote site, defaulted to rubygems.org

but I tried in ruby 1.8.6, 1.8.7, and 1.9.2, and it all says

in `<main>': uninitialized constant Gem::RemoteInstaller (NameError)

I already tried 

require 'rubygems'

and even

require 'rubygems/remote_installer'

Is there a new way to search using Gem inside of Ruby?

(please don't give answers such as system("gem list rails")

Gem::RemoteInstaller has been removed from the rubygems since version 1.0. This was a while ago. If you are looking for the ability to set someone up with gems that they may not have, I would strongly suggest bundler (actually I think all ruby projects should use it) http://gembundler.com

OK, you can try:

 require 'rubygems'
 r = Gem::SpecFetcher.new
 r.suggest_gems_from_name('rails')
 => ["rails"]
